  That brings another related question: is there any character
unsuported by GnuPG? I ask this because once I was using an application,
and I tried to use "special" characters in the password, but the app
rejected the users saying "wrong password", so I had to use just normal
characters. Is there a chance that problem can happen with GnuPG?
