Your post is a "bit" light on details.

But my Perl code doesn't recognises it.

We haven't seen your code, making it rather hard to diagnose and fix the problem it has.

Are there any PERL modules, using which I can handle the non-English text?

The name of the language is Perl, for starters.

What exactly do you want this module to do to the text? "Handle" could mean anything.
