I think "[[:punct:]]" is not a valid preg construction. I can be mistaken
but it looks like ereg, not preg.

I am not sure what lnguage it is :) To me it looks like a random set of
cyrillic letters. Normally I am able to recognize russian, unkranian,
belorussian and serbian.

Read about preg modifiers in PHP help. I think you need a unicode one +
UTF-8 encoding.
