How to form the utf-8 supported patterns to use with ORO

Hello there,

I am using ORO package for datavalidation. My code is written to support
UTF-8 character set.
I am using Perl5Util class to match for characters and its working fine
with ASCII characters.
But how do I validate the unicode charcters? If there is any unicode
characters in my source input the page returns blank without
throwing any error message. Please respond quickly.

Thanks,
