I am trying to write a validation function that would allow me to detect any
UTF-8 characters
Just to give the context -- its a user driven program and we would like to
detect when the user has entered any UTF-8 character Vs. only ASCII
characters.
An expression something like this : "[a-zA-Z][\\w\\-]{2,31}" would allow to
enter the ascii characters
Is there a way by way of expressions that I can detect if the user is
entering UTF-8 characters ... \u or \x something of that sorts...
any help would be greatly appreciated..
many thanks
