regex to match a character only if not followed by another character, then replace just that initial character
by Octopuss in Programming Languages

does that title make sense?

For instance, (/=[^>]/, '═')
I'd like to keep that match, but only replace the equals sign with the double-horizontal-line. As it is, it matches any '=' that is followed by anything that isn't a '>' but then replaces both the '=' and the following character with the replacing character, I want to keep the following character, but replace just the

I'm trying to read character by character from a text file until EOF, put them into a character array, so that I can manipulate it after. Compiled with g++ without errors, and when run, I'm prompted for the input file but then it just hangs.

Android. Replace a character with a character from numeric character reference
by CyberGreg in Programming Languages

How to get the length of a string containing character references while counting the character references as one single character?
by UglyCasanova in Programming Languages

How can I get the length of string that also contains character references? I want to count only the number of characters which will be displayed in the browser. Like

Restricting a special character in a text and allowing the same character only after a comma using Regular expression
by jasonmoo in Programming Languages

How do I create a regular expression for such condition?

Prevent unidentified character in ActiveSupport::Inflector.transliterate being replaced by ? (or the replacement character)
by Vytautas in Programming Languages

The documentation of ActiveSupport::Inflector.transliterate states:

Replaces non-ASCII characters with an ASCII approximation, or if none exists, a replacement character which defaults to "?".

I want that the characters for which approximations are not available, remain as it is. e.g.

by itsmegb in Development Tools & Services

Basically, I'm looking for a way to draw 255 images (ASCII character set) of a specific font. I would like each character to be drawn on a black background (white letter), and the image shouldn't be any bigger than the size of the character. Would be very appreciative towards any help. Thanks.
