I am having issues with the special CSV interpreter (no idea what its called) on iPad mobile browser.
iPad appears to reserve the character " as reserved or special. When this character appears the string is treated as a literal instead of seperated as a CSV.
INPUT:
1111,64-1111-11,Some Tool 12", 112233
Give the input above, the CSV mobile-safari display shows ([] represents a column)
[1111] [64-1111-11] [Some Tool 12, 112233]
Note that the " is missing. Also note that 112233 is not in its own column like it should be.
Question 2:
How can I get the CSV display tool in safari to not treat a six digit number as a phone number?
1234567
Shows up as a hyperlink and asks to "Add Contact" when I click it. I do not want the hyperlink.
UPDATE
iPad is ignoring the escape character (or backslash is not the escape character) for double quotes in CSV files. I am looking at the hex version of the file and I have
\" or 5C 22 (in hex with UTF-8 encoding).
Unfortuntely, the iPad displays the backslash and still treats " as a special character, thereby corrupting my data formatting. Anybody know how I can possibly use " on iPad CSV?
With regards the quotes, have you tried escaping them in the output?
EDIT: conventional escaping doesn't work for CSV files, my apologies. Most specifications state the following:
Fields that contain a special character (comma, newline, or double quote), must be enclosed in double quotes.
So, testing this on your CSV snippet, a file formatted like this:
1111,64-1111-11,"Some Tool 12""", 112233
or even like this:
1111,64-1111-11,Some Tool 12"""", 112233
… opens in Mobile Safari OK. How good or bad that looks in Excel you'd need to check.
Moving to the second issue, to prevent Mobile Safari from presenting numbers as phone numbers, add this to your page's head element:
<meta name="format-detection" content="telephone=no" />

I'm using Sublime Text for Latex, so i need to use a specific encoding. However, in some cases, when I paste text copied from a different program (word/browser in most cases), I'm getting the message:
"Not all characters are representable in XXX encoding, falling back to UTF-8"
My question is: Is there any way to see which parts of the text cannot be encoded, so I can delete them manually?
I had this problem. It is caused by corrupt characters in your document. Here is how i solved it.
1) Make a search in your document for all standard characters. Make sure you enable regular expressions in your search, then paste this :
[^a-zA-Z0-9 -\.;<>/ ={}\[\]\^\?_\\\|:\r\n#]
You can add to that the normal accented characters of your language, here are the characters for French and German. Such as éà and so on :
[^a-zA-Z0-9 -\.;<>/ ='{}\[\]\^\?_\\\|:\r\n~#éàèêîôâûçäöüÄÖÜß]
2) Search for that, and Keep pressing F3 until you see mangled characters. Usually something like "è" which is a corrupt version of "à".
3) Delete those characters or replace them with what they should be.
You will be able to convert the document to another encoding when you have cleared all corrupt characters out.
For Linux users, it's also possible to automatically remove broken characters with command iconv:
iconv -f UTF-8 -t Windows-1251 -c < ~/temp/data.csv > ~/temp/data01.csv
-c Silently discard characters that cannot be converted instead of terminating when encountering such characters.
Just adding to #Draken response: here is the RegEx with spanish characters added.
[^a-zA-Z0-9 -\.;<>/ =“”'{}\[\]\^\?_\\\|:\r\n~#àèêîôâûçäöüÄÖÜßáéíóúñÑ¿€]
In my case I hitted Ctrl+H (for replacement) and as a replacement expression used nothing. So everything got cleared super fast and I was able to save it using ISO-8859-1.
I am using librets to retrieve data form my RETS Server. Somehow librets Encoding method is not working and I am receiving some weird characters in my output. I noticed characters like '’' is replaced with ’. I am unable to find a fix for librets so i decided to replace such garbage characeters with actual values after downloading data. What I need is a list of such garbage string and their equivalent characters. I googled for this but not found any resource. Can anyone point me to the list of such garbage letters and their actual values or a piece of code which can generate such letter.
thanx
Search for the term "UTF-8", because that's what you're seeing.
UTF-8 is a way of representing Unicode characters as a sequence of bytes. ("Unicode characters" are the full range of letters and symbols used all in human languages.) Typically, one Unicode character becomes 1, 2, or 3 bytes in UTF-8. When those bytes (numbers from 0 to 255) are displayed using the character set normally used by Windows, they appear as "garbage" -- in this case, 3 "garbage letters" which are really the 3 bytes of a UTF-8 encoding.
In your example, you started with the smart quote character ’. Its representation in Unicode is the number 8217, or U+2019 (2019 is the hexadecimal for 8217). (Search for "Unicode" for a complete list of Unicode characters and their numbers.) The UTF-8 representation of the number 8217 is the three byte sequence 226, 128, 153. And when you display those three bytes as characters, using the Windows "CP-1252" character encoding (the ordinary way of displaying text on Windows in the USA), they appear as ’. (Search for "CP-1252" to see a table of bytes and characters.)
I don't have any list for you. But you could make one if you wrote a program in a language that has built-in support for Unicode and UTF-8. All I can do is explain what you are seeing.
If there is a way to tell librets to use UTF-8 when downloading, that might automatically solve your problem. I don't know anything about librets, but now that you know the term "UTF-8" you might be able to make progress.
Question reminder:
"...I noticed characters like '’' is replaced with ’... i decided to
replace such garbage characeters with actual values after downloading
data. What I need is a list of such garbage string and their
equivalent characters."
Strictly dealing with this part:
"What I need is a list of such garbage string and their equivalent
characters."
Using php, you can generate these characters and their equivalence. Working with all 1,111,998 Unicode points or 109,449 Utf8 symbols is impractical. You may use the ASCII range in the following loop between € and Ă or another range that is more relevant to your context.
<?php
for ($i=128; $i<258; $i++)
$tmp1 .= "<tr><td>".htmlentities("&#$i;")."</td><td>".html_entity_decode("&#".$i.";",ENT_NOQUOTES,"utf-8")."</td><td>&#".$i.";</td></tr>";
echo "<table border=1>
<tr><td>&#</td><td>"Garbage"</td><td>symbol</td></tr>";
echo $tmp1;
echo "</table>";
?>
From experience, in an ASCII context, most "garbage" symbols originate in the range € to ā + (seldom) ῁ to ‶.
In order for the "garbage" symbols to display, the html page charset must be set to iso-1 or whichever other charset that caused the problem in the first place. They will not show if the charset is set to utf-8.
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
.
"i decided to replace such garbage characeters with actual values
after downloading data"
You CANNOT undo the "garbage" with php utf8_decode(), which would actually create more "garbage" on already "garbage". But, you may use the simple and fast search and replace php str_replace() function.
First, generate 2 arrays for each set of "garbage" symbols you wish to replace. The first array is the Search term:
<?php
//ISO 8859-1 (Latin-1) special chars are found in the range 128 to 257
$tmp1 = "\$SearchArr = array(";
for ($i=128; $i<258; $i++)
$tmp1 .= "\"".html_entity_decode("&#".$i.";",ENT_NOQUOTES,"utf-8")."\", ";
$tmp1 = substr($tmp1,0,strlen($tmp1)-2);//erases last comma
$tmp1 .= ");";
$tmp1 = htmlentities($tmp1,ENT_NOQUOTES,"utf-8");
?>
The second array is the replace term:
<?php
//Adapt for your relevant range.
$tmp2 = "\$ReplaceArr = array(\n";
for ($i=128; $i<258; $i++)
$tmp2 .= "\"&#".$i.";\", ";
$tmp2 = substr($tmp2,0,strlen($tmp2)-2);//erases last comma
$tmp2 .= ");";
echo $tmp1."\n<br><br>\n";
echo $tmp2."\n";
?>
Now, you've got 2 arrays that you can copy and paste to use and reuse to clean any of your infected strings like this:
$InfectedString = str_replace($SearchArr,$ReplaceArr,$InfectedString);
Note: utf8_decode() is of no help for cleaning up "garbage" symbols. But, it can be used to prevent further contamination. Alternatively a mb_ function can be useful.
text.scan(/\"[\d\w\s\+\-\*\/]*\"/)
I'm simply looking to find any thing within quotations that can contain letters, numbers, spaces, plus, minus, star, or forward slash. Everything works great in console. Each of the following works in a browser:
"abc"
"123"
"x-1" or "x - 1"
"x/1" or "x / 1"
But the plus sign and star fail in a browser (despite working fine in console with the same regex). Does anyone have any ideas?
Edit #1: I'm performing a quick gsub to add some formatting to the results of the scan. If the quotations have a plus or star in them, they don't even get picked up by the scan. The same code and text pasted in console works just fine.
Edit #2: I figured out a better way to frame this question without extraneous details and got the answer. "Why can't I perform a gsub on each of the results from a scan if the result contains regex special characters?"
Turned out that this problem was related to regexp string insertion (/#{whatever}/) not escaping special characters - manually escaping clears it up (/#{Regexp.escape(whatever)}/). See this question for a full example/explanation.
I don't know what do you mean "work in browser" but I'm making an assumption that you're trying to parse an URL. In URL the + & * signs can be converted to %2B & %2A respectively.
Try this regexp:
/"[(\d\w\s\+\-\*\/|%2B|%2A)]+"/
...or decode URL before parsing.
I've hit a problem during parsing of a CSV file where I get the following error:
CSV::MalformedCSVError: Illegal quoting on line 3.
RAILS code in question:
csv = CSV.read(args.local_file_path, col_sep: "\t", headers: true)
Line 3 in the CSV file is:
A-067067 VO VIA CE 0 8 8 SWCH Ter 4, Loc Is Here, Mne, Per Fl Auia/Sey IMAC NEK_HW 2011-03-09 09:47:44 2011-03-09 11:50:26 2011-01-13 10:49:17 2011-02-14 14:02:43 2011-02-14 14:02:44 0 0 771 771 46273 "[O/H 15/02] B270 W31 ""TEXT TEXT 2 X TEXT SWITC" SOME_TEXT SOME_TEXT N/A Name Here RESOLVED_CLOSED RESOLVED_CLOSED
UPDATE: Tabs don't appear to have come across above. See pastebin RAW TEXT: http://pastebin.com/4gj7iUpP
I've read numerous threads all over StackOverflow and Google about why this is and I understand that. But the CSV row above has perfectly legal quoting does it not?
The CSV is tab delimited and there is only a tab followed by the quote on either side of the column in question. There is 1 quote in that field and it is double quoted to escape it. So what gives? I can't work it out. :(
Assuming I've got something wrong here, I'd like the solution to include a way to work around the issue as I don't have control over how the CSV is constructed.
This part of your CSV is at fault:
46273 "[O/H 15/02] B270 W31 ""TEXT TEXT 2 X TEXT SWITC" SOME_TEXT
At least one of these parts has a stray space:
46273 "
" SOME_TEXT
I'd guess that the "3" and the double are supposed to be separated by one or more tabs but there is a space before the quote. Or, there is a space after the quote on the other end when there are only supposed to be tabs between the closing quote and the "S".
CSV escapes double quotes by double them so this:
"[O/H 15/02] B270 W31 ""TEXT TEXT 2 X TEXT SWITC"
is supposed to be a single filed that contains an embedded quote:
[O/H 15/02] B270 W31 "TEXT TEXT 2 X TEXT SWITC
If you have a space before the first quote or after the last quote then, since your fields are tab delimited, you have an unescaped double quote inside a field and that's where your "illegal quoting" error comes from.
Try sending your CSV file through cat -t (which should represent tabs as ^I) to find where the stray space is.
let's say that I have an XML file containing this :
<description><![CDATA[
<h2>lorem ipsum</h2>
<p>some text</p>
]]></description>
that I want to get and parse in ActionScript 2 as HTML text, and setting some CSS before displaying it. Problem is, Flash takes those whitespaces (line feed and tab) and display it as it is.
<some whitespace here>
lorem ipsum
some text
where the output I want is
lorem ipsum
some text
I know that I could remove the whitespaces directly from the XML file (the Flash developer at my workplace also suggests this. I guess that he doesn't have any idea on how to do this [sigh]). But by doing this, it would be difficult to read the section in the XML file, especially when lots of tags are involved and that makes editing more difficult.
So now, I'm looking for a way to strip those whitespaces in ActionScript. I've tried to use PHP's str_replace equivalent (got it from here). But what should I use as a needle (string to search) ? (I've tried to put in "\t" and "\r", don't seem to be able to detect those whitespaces).
edit :
now that I've tried to throw in newline as a needle, it works (meaning that newline successfully got stripped).
mystring = str_replace(newline, '', mystring);
But, newlines only got stripped once, meaning that in every consecutive newlines, (eg. a newline followed by another newline) only one newline can be stripped away.
Now, I don't see that this as a problem in the str_replace function, since every consecutive character other than newline get stripped away just fine.
Pretty much confused about how stuff like this is handled in ActionScript. :-s
edit 2:
I've tried str_replace -ing everything I know of, \n, \r, \t, newline, and tab (by pressing tab key). Replacing \n, \r, and \t seem to have no effect whatsoever.
I know that by successfully doing this, my content can never have real line breaks. That's exactly my intention. I could format the XML the way I want without Flash displaying any of the formatting stuff. :)
Several ways to approach this. Perhaps the simplest answer is, in one sense your Flash developer is probably right, and you should move your whitespace outside of the CDATA container. The reason being, many people (me at least) tend to assume that everything inside a CDATA is "real data", as opposed to markup. On the other hand, whitespace outside a CDATA is normally assumed to be irrelevant, so data like this:
<description>
<![CDATA[<h2>lorem ipsum</h2>
<p>some text</p>]]>
</description>
would be easier to understand and to work with. (The flash developer can use the XML.ignoreWhite property to ignore the whitespace outside the CDATA.)
With that said, if you're editing the XML by hand, then I can see why it would be easier to use the formatting you describe. However, if the extra whitespace is inside the CDATA, then it will inevitable be included in the String data you extract, so your only option is to grab the content of the CDATA and remove the whitespace afterwards.
Then your question reduces to "how do I strip leading/trailing whitespace from a String in AS2?". And unfortunately, since AS2 doesn't support RegEx there's no simple way to do this. I think your best option would be to parse through from the beginning and end to find the first/last non-white character. Something along these lines (untested pseudocode):
myString = stuffFromXML;
whitespace = " " + "\t" + "\n" + "\r" + newline;
start = 0;
end = myString.length;
while ( testString( myString.substr(start,1), whitespace ) ) { start++; }
while ( testString( myString.substr(end-1,1), whitespace ) ) { end--; }
trimmedString = myString.substring( start, end );
function testString( needle, haystack ) {
return ( haystack.indexOf( needle ) > -1 );
}
Hope that helps!
Edit: I notice that in your example you'd also need to remove tabs and whitespace within your text data. This would be tricky, unless you can guarantee that your data will never include "real" tabs in addition to the ones for formatting. No matter what you do with the CDATA tags, it would probably be wiser not to insert extraneous formatting inside your real content and then remove it programmatically afterward. That's just making your own life difficult.
Second edit: As for what character to remove to get rid of newlines, it depends partially on what characters are actually in the XML to begin with (which probably depends on what OS is running where the file is generated), and partially on what character the client machine (that's showing the flash) considers a newline. Lots of gory details here. In practice though, if you remove \r, \n, and \r\n, that usually does the trick. That's why I added both \r and \n to the "whitespace" string in my example code.
its been a while since I've tinkered with AS2.
someXML = new XML();
someXML.ignoreWhite = true;
if you wanted to str_replace try '\n'
Is there a reason that you are using cdata? Admittedly I have no idea what the best practice for this sort of this is, but I tend to leave them out and just have the HTML sit there inside the node.
var foo = node.childnodes.join("") parses it out just fine and I never seem to come across these whitespace problems.
I'm reading this over and over again, and if I'm interpreting you right, all you want to know how to do is strip certain characters (tabs and newlines) from a string in AS2, right? I cannot believe no one has given you the simple one line answer yet:
myString = myString.split("\n").join("");
That's it. Repeat that for \r, \n, and \t and all newlines and tabs will be gone. If you want it as an easy function, then do this:
function stripWhiteSpace(str: String) : String
{
return str.split("\r").join("").split("\n").join("").split("\t").join("");
}
That function won't modify your old string, it will return a new one without \r, \n, or \t. To actually modify the old string use that function like this:
myString = stripWhiteSpace(myString);
