Out of necessity I have created a little Windows application which will scan and analyize a given set of text, and produce a character class set for use in a regular expression.
So, if you have the text I am 28 years old., it will produce [a-z0-9\s\.]. It also allows you to specify which characters are special and need escaping.
Please note this tool requires .NET 2.0 to be installed on your computer. Cheers! :D
