Yes, theoretically you're right. But there's something weird with the
interaction on xterms. I've seen in mostly with slang applications, like
mutt and jed. They both display oddly and so forth in X. But slang
bypasses curses, as I recall, and uses the terminfo capabilities
directly. I typically don't run console apps under X, so I haven't
testing this stuff extensively.
Still, your problem with the insertion of odd characters doesn't sound
like a curses problem. Maybe a key mapping problem with X? Dunno.
Anyway....
