Finally decided to try searching again and found this site:

If we wish to believe it, then it is possible to have a short filename
containing characters Win95 can't/won't deal with that are always
replaced with a '_'.  It is also mentioned at
http://catless.ncl.ac.uk/Risks/18.06.html again not a definitive
source.

http://support.microsoft.com/kb/120138 and
http://support.microsoft.com/kb/154997/EN-US/ might give more info
also.

I'm going to try to create some "funny" filenames in a Windows 95 VM I
just built to test.
