Well, if your U-ICHIGO\.... part is in Unicode, I can see why it would
confuse the passwd parsing routines (in particular, internal_getpwsid()),
which only deal with regular 1-byte characters.  I'm not sure, though,
that changing the name part of the gecos field would make password
authentication work -- perhaps Pierre or Corinna would comment on this.
