Which character is used to fill contents of password text input? - character-encoding

I need this filled-circle character for my sketch of the UI.
I have not found it in characters table on my mac.

I'm not sure which is the exact one on the mac, but bullet is probably what you want to search for.
or use • unicode 2022.
or alternatively ⚫ 26AB (medium black circle) or ● 25CF (black circle)

Slight FROWNING face unicode in iOS

I want to display slightly FROWNING face in my UILabel and the unicode whihc i am using is \u2639 but that's displaying white frowny face but i needed the yellow one. I checked everywhere but its the same unicode everywhere. could somebody tell me what is the unicode for yellow frowning face?
Edit - Attached is the screenshot for which i am looking for unicode which should be the one which i posted above but that is giving me white frowning face not the yellow one.
The slightly frowny face is U+1F641.
However, let's return to your original question. You are setting the label's text to "\u{2639}" and you are seeing the white frowny face.
The solution is to specify the variant of this glyph, like this: "\u{2639}\u{FE0F}". If you set the label's text to that, you will see the yellow frowny face.
(To understand why that is and what the variation selector means, see https://unicode.org/reports/tr51/#Emoji_Variation_Sequences. Basically, this unicode codepoint falls in the older text area, so if you want the newer emoji variant, you have to ask for it.)
But an even simpler solution is: don't use codepoint values at all! Swift strings are unicode. Just include the emoji directly in your string. Set the label's text to "☹️"! For example:
self.label.text = "☹️"
That way, you will see the emoji you specified in the string.

Special unicode characters in TButton.Caption (instead of icons)

Is it possible to enter from keyboard special Unicode characters, link the ones below?
U+2603 ☃ SNOWMAN
U+2604 ☄ COMET
U+2605 ★ BLACK STAR
U+2606 ☆ WHITE STAR
U+2607 ☇ LIGHTNING
U+2608 ☈ THUNDERSTORM
U+2609 ☉ SUN
U+260A ☊ ASCENDING NODE
U+260B ☋ DESCENDING NODE
I would like for example to have buttons with up/down arrows in them, without loading images.
I have tried entering Alt+08593 on keyboard but other character (than the expected arrow) will be inserted.
Update:
The reason for this is LAZINESS. I am too lazy to search for icons or create my own icons. For example you can simply replace the notorious 'save' floppy disk icon. Just take a look at: 💾. BAM! Nice. Right?
Update:
It seems some characters such as 📗 (green book = 128215) are not accepted by Delphi, with copy/paste.
Update:
There is nice component that allows you to put unicode chanracters in a image list:
https://github.com/EtheaDev/IconFontsImageList
The Delphi IDE won't accept ALT key codes that high. A couple of alternatives:
Paste the text from somewhere else.
Enter the numeric code directly in the .dfm file.
As an example of the second approach, try this in your .dfm file for the button caption property:
Caption = #8592#8593#8594#8595
You also mention Green Book U+1F4D7. That is from outside the BMP, and hence encoded with a surrogate pair:
Caption = #55357#56535
My guess is that as soon as you want your glyphs to be shown in colour, or at a different size, you will find that using text makes this impossible. You are also likely to encounter fonts that don't contain glyphs for the characters you select. So you will find that using images is the most robust approach.
Or, alternatively, if you had a table of the decimal values:
9731 ☃ SNOWMAN
9732 ☄ COMET
9733 ★ BLACK STAR
9734 ☆ WHITE STAR
9735 ☇ LIGHTNING
9736 ☈ THUNDERSTORM
9737 ☉ SUN
9738 ☊ ASCENDING NODE
9739 ☋ DESCENDING NODE
then you can use the keyboard as follows in Delphi.
To change the caption of Button1 to be the snowman:
Press Alt+F12 to edit the form as text
Press Ctrl+E to enter incremental search mode
Type Button1, or as much of it as is required to locate the definition of Button1
To the right of the Caption = property definition (I'm assuming VCL here) enter # followed by the relevant Unicode value, e.g. #9731
Caption = #9731
If you want text as well as the snowman, the character code goes outside quotes, so e.g.
Caption = 'Snowman = '#9731
More info on the # syntax (which is more commonly entered in Delphi source, rather than in the text view of form files) can be found by reading about control strings, as they are actually called, in the online documentation.

How to obtain plain 'globe' Unicode character

If you include Unicode characters in an NSString, a lot of them will take on the color set for that text - they're just regular glyphs for that font so they're displayed like any other character. But there are some Unicode characters that are colored, for example GLOBE WITH MERIDIANS which is a blue gradient with shadows. But I have seen this same glyph elsewhere that's a simple black outline without a shadow, for example in the iOS keyboard. I would like to use that glyph, but without the adornments, and without having to create and use an image. I wondered if a different font would render it in a different format, and while iOSFonts.com does show different styles (bolder, italics), they're all blue. Is it possible to get the simple plain version?
Surely it is possible, because that appears to be exactly what Apple has implemented with a Tip. Notice the globe is the exact same color as the text and it's included in the string along with all the other characters. Surely that's not a UIImage?
Character in different fonts:
EDIT: The solution provided in the linked question doesn't work for this character, as the variant character appears to be the exact same as the original - blue with shadows.
Unfortunately, iOS doesn't have a monochrome globe symbol you can use; the only built-in font that includes U+1F310 GLOBE WITH MERIDIANS is Apple Color Emoji.
If you really want a font that renders this character as a simple black outline, you could package a copy of Symbola (downloadable here) into your app.
Alternatively, you could make a bitmap image with the icon you want and use NSTextAttachment to put it into an attributed string. Apple is likely doing something along these lines, as many of their Tips include symbols that are definitely not Unicode characters:

What is a vertical tab?

What was the original historical use of the vertical tab character (\v in the C language, ASCII 11)?
Did it ever have a key on a keyboard? How did someone generate it?
Is there any language or system still in use today where the vertical tab character does something interesting and useful?
Vertical tab was used to speed up printer vertical movement. Some printers used special tab belts with various tab spots. This helped align content on forms. VT to header space, fill in header, VT to body area, fill in lines, VT to form footer. Generally it was coded in the program as a character constant. From the keyboard, it would be CTRL-K.
I don't believe anyone would have a reason to use it any more. Most forms are generated in a printer control language like postscript.
#Talvi Wilson noted it used in python '\v'.
print("hello\vworld")
Output:
hello
world
The above output appears to result in the default vertical size being one line. I have tested with perl "\013" and the same output occurs. This could be used to do line feed without a carriage return on devices with convert linefeed to carriage-return + linefeed.
Microsoft Word uses VT as a line separator in order to distinguish it from the normal new line function, which is used as a paragraph separator.
In the medical industry, VT is used as the start of frame character in the MLLP/LLP/HLLP protocols that are used to frame HL-7 data, which has been a standard for medical exchange since the late 80s and is still in wide use.
It was used during the typewriter era to move down a page to the next vertical stop, typically spaced 6 lines apart (much the same way horizontal tabs move along a line by 8 characters).
In modern day settings, the vt is of very little, if any, significance.
The ASCII vertical tab (\x0B)is still used in some databases and file formats as a new line WITHIN a field. For example:
In the .mer file format to allow new lines within a data field,
FileMaker databases can use vertical tabs as a linefeed (see https://support.microsoft.com/en-gb/kb/59096).
I have found that the VT char is used in pptx text boxes at the end of each line shown in the box in oder to adjust the text to the size of the box.
It seems to be automatically generated by powerpoint (not introduced by the user) in order to move the text to the next line and fix the complete text block to the text box. In the example below, in the position of §:
"This is a text §
inside a text box"
A vertical tab was the opposite of a line feed i.e. it went upwards by one line. It had nothing to do with tab positions. If you want to prove this, try it on an RS232 terminal.
similar to R0byn's experience, i was experimenting with a Powerpoint slide presentation and dumped out the main body of text on the slide, finding that all the places where one would typically find carriage return (ASCII 13/0x0d/^M) or line feed/new line (ASCII 10/0x0a/^J) characters, it uses vertical tab (ASCII 11/0x0b/^K) instead, presumably for the exact reason that dan04 described above for Word: to serve as a "newline" while staying within the same paragraph. good question though as i totally thought this character would be as useless as a teletype terminal today.
I believe it's still being used, not sure exactly. There might be even a key combination of it.
As English is written Left to Right, Arabic Right to Left, there are languages in world that are also written top to bottom. In that case a vertical tab might be useful same as the horizontal tab is used for English text.
I tried searching, but couldn't find anything useful yet.

how to display custom quotation marks with sifr?

I have some text and quotation marks around it, but I want each of them to be a different font to be replaced by sifr. The problem is that the quotes need to go exactly around the text, but the text once turned into an tag becomes a block and the text isn't shaped necessarily like a rectangle. I thought about having the quotes be background images of the replaced text, but only safari 3 supports multiple background images. Any suggestions?
I don't think Flash provides enough control over text elements to get this as precise as you'd like.
