I really don't understand the problem here - as far as I know all
characters can be used in URLs so long as they are properly escaped. If
your server software is not coping with that for some reason then I
think it's a bug.
As a test I just created a file called '<>&+?#;%.html' in an apache
served directory and then asked Firefox to fetch:
and it was retrieved just fine.
