Regular expression for punctuation

[Chris Leffer]

Hi.

I am trying to define a regular expression that accepts letters and
punctuation characters. I read something about Posix where I could use
[unct:] in order to accept all the punctuation characters, but I could
not find how to add this to my expression. My expression is a simple
[A-Za-z]. How can I make it accept all the punctuation characters also?

Regards,
