yes, other characters are potentially dangerous, eg:

  "foo\"; rm -rf ."

or %, for example if someone used %H in a netbios name, samba would
later replace it with a home directory.

It may be that we can safely allow for any non-7bit chars. The risk
then is if the filesystem on the machine strips off the 8th bit and
that produces a "/". Nasty.

I'm not sure what the best way to handle this is. Suggestions?
