[aleksa77]

What si regex for -remove all but except letters and numbers.

I grab some title, this title to be name of txt file, example :

***A Celebration Of Jessica Biel ^ &2012***

txt file can not create if have some special characters.

I find some code for find all special characters:

[^a-zA-Z0-9 ]

But can not remove?
