what is your definition of an "illegal character"?

[Archit Gupta]

basically i want to check use of characters other than space,'(',')' n alphabets...

[Dormilich]

define "alphabets" (if you’re considering Unicode, that accounts for more than 10,000 characters)

then your illegal characters are roughly [^\w ] (still includes underscore) or [0-9a-z ] (using the i parameter)

yes...but [^\w] includes space. n i dont want it as an illegal character in the if statement in my first post on this thread...
