hello guys.

i am trying to write some script.. which has two files
1. html form with text input fields...

in one of them i want to allow writing info (name) in georgian language (no other language letters to be allowed neither ,.;:*#&$ or this kinda chars..

so if it was ENGLISH it would be easy to use preg_match A-Z-a-z or somethig like that.. but what should i do when i want different language?

any suggestations will be appriciated.
thank you
