for regexp, if you wanted the first character to be alphanumeric, non-space

^[a-zA-Z0-9][a-zA-Z0-9 ]+$

of course, that will allow an ending space character, which could eliminate with something like:

^[a-zA-Z0-9][a-zA-Z0-9 ]+[a-zA-Z0-9]$

however, that still allows multi-space runs in the middle.

One thing I always tell my guys -- validate input, don't try and fix it. Running search and replace to destroy invalid string or url encoding, etc can be avoided with a decent regexp.
