PDF Plugin needs to be able to handle spaces in filenames

The (otherwise excellent) PDF plugin can't process uploaded files that include spaces or foreign characters.

Many of my users are on Apple PCs or tablets and aren't familiar with the usual filenaming conventions.

Maybe a bit of REGEX in the code could do a bit of automatic substitution?

I wrote a PHP upload routine a while ago that could replace spaces, but I never got around to stripping out foreign/illegal characters - so it *ought* to be possible ;-)
