note 88128 rejected from function.preg-match by danbrown

Note Submitter: onge ---- There is an problem with PREG_OFFSET_CAPTURE flag and multibyte strings - it return number of bytes, rather than number of characters. So, if you want to use it for example to truncate text around found expression using mb_substr, you cant use offset number (because mb_substr DOES count characters, not bytes). With use of standard substr it seems it works, but sometimes it "slice multibyte character in middle", so you get invalid character displayed. I havent found sufficient solution yet.
