PREG_OFFSET_CAPTURE returns wrong offset if there is a multibyte character

Function preg_match_all($pattern, $subject, PREG_OFFSET_CAPTURE ) returns wrong offset for matched value if there are multibyte characters in subject.
It seems that PHP counts multibyte character as two characters instead of one.

Is there a solution to this problem?

Is that what you want to do? Find out the "character" position for a match's byte position?

You're only giving out small pieces of information at a time. It's hard to give advice on broader problems or situations when we have to work with is your use of mb_strlen and substr...

Yes, I am using regex preg_match_all to find offset of matches so that I could use substr to the position of PREG_OFFSET_CAPTURE.
And then I would use mb_strlen(substr($text, 0, $offset_capture))
to find "real" offset if there are multibytes in the text.
