#1 Text Regex

My regex is incorrect, what should I change?
Search for text with characters in one line.

^([\p{Cyrillic}]+[\-\.\,\!\…\?\(\)\„\”—0-9\s]+[\p{Cyrillic}\-\.\,\!\…\?\(\)\„\”—0-9\s]*|[\-\.\,\…\?\(\)\„\”—0-9]+[\p{Cyrillic}]+[\p{Cyrillic}\-\.\,\!\…\?\(\)\„\”—0-9\s]*)$

Text included:
\p{Cyrillic}
!
!!
!!!
!!!!
?
??
???
… (unicode)
— (unicode)

0-9

„ (unicode)

\s (space)

Still wrong:

^([\p{Cyrillic}]+[\-\.\,\!\…\?\(\)\„\”\,\;\\\/\*\#\@\&\:\.x{200B}—0-9\s]+[\p{Cyrillic}\-\.\,\!\…\?\(\)\„\”\,\;\\\/\*\#\@\&\:\.x{200B}—0-9\s]*|[\-\.\,\…\?\(\)\„\”\,\;\\\/\*\#\@\&\:\.x{200B}—0-9\s]+[\p{Cyrillic}]+[\p{Cyrillic}\-\.\,\!\…\?\(\)\„\”\,\;\\\/\*\#\@\&\:\.x{200B}—0-9\s]*)$

Hi,
PSPad regex engine doesn't currently support several features you are using in your pattern:

e.g. the unicode properties \p{...} (e.g. \p{Cyrillic}) refering to unicode block or script or codepoint matching using \x{...} (there must be a backslash before x in this notation, or it is handled litterally, i.e. it had to be \x{200B} in a tool that supports it to match
# ​ (dec.: 8203) (hex.: 0x200b) # ​ ZERO WIDTH SPACE (Other, Format) (General Punctuation [8192-8303] [0x2000-0x206f])

you may use another tools that currently support these features, or it might be possible to replace the properties with character sets,
e.g. with [Ѐ-ԯ] you can match all codepoinds in the ranges 0x0400-0x04FF; Cyrillic and 0x0500-0x052F; Cyrillic Supplement
which might be sufficient for some usecases.

The codepoint or unicode notation is not supported - the respective characters must be entered directly in the pattern.

hth,

But with Cyrillic I have no problems, I can replace the standard regex working in PSPad or other editor, but what about the next code? I can not deal with him.

Ok, the zero width space can be problematic too, but it can be copied directly and in can be handled in PSPad, even in search dialog - it should be the "invisible" character between the following parens:
(​)
UNfortunatley, the editor component in PSPad has som problems with selection of such characters, but it is in general possible to select/copy larger part of the surrounding test and (carefully) delet the other parts as needed.
It is also shown the same likeregular space in pspad as a dot marking whitespace.

Ok, let's get rid of "ZERO WIDTH SPACE", I'm talking about normal Regex, let's not talk about Unicode anymore.

\char = match a literal

How to match all characters from the above on the forum?

Hi, what is the pattern supposed to match? - probably some (preferably short) samples of real text strings might be clearer.
If Cyrillic or some "special" - i.e. non-ascii punctuation should be matched, unicode definitely needs to be taken into account.
The current patterns are most likely more complicated than needed - e.g. you don't need escaping most of the literals in the character class (between [...]) - most likely only: - ^ [ and ] (with some further positional specificities).

I will not give examples because there are too many different ones and a more accurate match would have been needed. There is no point in matching everything! It would be very bad. And that this is my work - I will not write private texts.
It simply has to contain Russian words and all char that I gave in early. That's all.
