I thought about that and have (I think they are in the code) created 
regexps that disallow only characters reserved in URLs, HTML/XML and file 
systems.

But then again, I was afraid to start the discussion and hold up the patch 
because of it.

Spaces are not allowed in URLs, but file names will be used in URLs.

Dangerous characters:

file system: * | \ / : < > ? " non-printables
URL: # % { } [ ] | \ ^ ~ ` space
HTML: & < > "

Additionally TYOP3 doesn't like commas as it uses them as separators in 
group fields. Which could be change and handled by update scripts ;-)
