Problem with the PCRE engine,
does not search for some Unicode.

regex:[^\x{200B}]

I would ask for a compatible Regex for Everything (PCRE), for Boost.Regex and .NET Regex

You are searching for all characters except 200B (Unicode Character 'ZERO WIDTH SPACE'). Its what everything did. (NOT 200B).

As 200B is invisible character, even if EmEditor/Notepad++/others finds it and moves cursor to the position, We may not see the cursor.

So try this
.\x{200B}.

It will find 3 characters (but shows 2 characters) and the middle character is ZWSP. So you know where the Zerowidth Space is.

(NB:Tried with Notepad++ and EmEditor and it works)

Glad it worked. But it will not work if the ZWSP is in the beginning or at the end of line.
