Regex.replace

Replaces all occurrences of the pattern in regex with the replacement text. Backreferences of the form '\number' or '\g<number>' in the replacement text are interpolated by the number-th captured subexpression of the match, '\g<name>' refers to the captured subexpression with the given name. '\0' refers to the complete match, but '\0' followed by a number is the octal representation of a character. To include a literal '\' in the replacement, write '\\\\'.

There are also escapes that changes the case of the following text:

- \l: Convert to lower case the next character - \u: Convert to upper case the next character - \L: Convert to lower case till \E - \U: Convert to upper case till \E - \E: End case modification

If you do not need to use backreferences use Regex.replaceLiteral.

The replacement string must be UTF-8 encoded even if G_REGEX_RAW was passed to Regex.new. If you want to use not UTF-8 encoded stings you can use Regex.replaceLiteral.

Setting start_position differs from just passing over a shortened string and setting G_REGEX_MATCH_NOTBOL in the case of a pattern that begins with any kind of lookbehind assertion, such as "\b".
