Regex for legal file name chars

[WLT]

I need to filter out non-legal characters from potential
(user-entered) file names. Certainly this must exist already.

Also...I remember there was a large cache of regex strings online
somewhere but I can't remember the site name. It wasn't regex.com
(though there is a nice fuzzy animal there). Anyone?

PS: It would be very nice to find both Unicode and Ascii versions of
the file name filter.

No reply to this yet. I thought that would be an easy one (you can
tell I'm trying to avoid a jumble of letters if I possibly can).

So...If no one has a regex string to do this, do you know the URL of
the large Regex site? I thought it was regex.com but apparently not.

Answering my own question... Just found the site again:
http://regexlib.com/Search.aspx

Searching for "File Name" and for "Filename" turned up a few strings.
