regular pattern

[Parashuram Hallur]

Hi,

I am looking for regular pattern which will check for the characters
0-9a-zA-Z and '_' and non-ascii characters

If the input string contains any of the above characters should be allowed. Essentially I want to restrict only special characters but not non-ascii.

Thanks for any help
