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.
