I have a string from user input that is in the following format:
"foo\U+FFE2\U+FFB5\U+FFE2\U+FFB5"
When I view this it does not show anything in the browser or terminal, but they are definitely there.
What are they and how do I remove all junk chars like these to end up with just 'foo'?
I know I could just remove these specific ones but there maybe other different ones that I want just the text value from.
Any ideas?
I see the two main variants:
with #split/#join pair:
"fooффф".split('').select{|x|x.ord <= 127}.join
# => "foo"
with #unpack/#pack pair:
"fooффф".unpack('U*').select{|x| x <= 127}.pack('U*')
# => "foo"

I have a global variable, but when I give the value of the variable does not change when I
run in viewDidload, this is my code :
(https://pastebin.com/7QbBjLNC)
The data is being fetched asynchronously and the print statement is getting executed before the response is received. print the data after you assign value to self.jumlahStok

So I found out that any variable or constant in swift is a tuple. For example, variable x below is a tuple
var x = 15
and following statement is valid and evaluates to value of x as the first element of tuple
x.0.0.0.0.0.0.0.0.0.0.0 // outputs 15
I'm wondering why the language has been built to accommodate this. Any known (or outworldly) use case?
I don't know can it be the right answer, but it gives some information and shows that it's a known thing. Look this 2 sections:
Special: The 1-Tuple
Bonus Track: Tuples All the Way Down

How to write something
if !inBoundary then do
printfn "no it's not within the boundary"
You can use the not built-in function (and omit the do keyword after then):
let inBoundary = false
if not inBoundary then
printfn "no it's not within the boundary"

Im using ruby and rails to automatically create a filename from the name of the product and the product's variant-type. Using .gsub, the filename will be lowercase and have special characters (spaces, ', -) removed. Ive got most of it working but I can't seem to get it to remove double quotes.
This works for single quotes:
"'"
But this doesn't work for double-quotes:
'"'
Here's my code:
filepath_name = product.name+"_"+variant_type.gsub(/ /,'').gsub("'", "").gsub("-", "").gsub('"', '').downcase+".mpg"
You could just use a regexp to remove anything but ascii characters like:
variant_type.gsub!(/[^0-9A-Za-z.\-]/, '')
and modify it to suit your needs. You can use rubular for a reference.

I have an arbitratry string, something like QKOTRFLARGEBRAAFFALGORITHMMIMISSSTUPIDCROCODOLCONCEALEDKSBABA...
and I need to tell LaTeX to split this string neatly into lines. It is not a word, there should be no '-' when splitting line. Just fit these data into lines, break wherever it suits.
I have successfully used the seqsplit package for that.
