[Mono-list] Regex dosen't recognize \s or \w ?

That'd cover "zero or more spaces", but wouldn't cover "zero or more
whitespace characters" (which is what "\s" would get you, and what I'm
assuming OP really wants, despite not *quite* being what they said in
their final quesion).

Do any escape characters work or is it just those? Don't forget that
regex escapes like \s are different to character escapes like \r, \n and
\t - you need to escape the backslash if you're using it in
double-quoted strings, or else it will be treated like a character
escape, not a special regex escape.

See the example at
for what I mean.
