Passphrase of GPG-generated key not accepted

Wouldn't it be a good idea to include character encoding information in
keys? I think so. Many people don't use UTF-8 yet. Demanding such
configuration like you mentioned from all these users sounds
unreasonable to me. Isn't a workaround possible? Since I use GTK+
applications for quite a while now and never experienced similar
problems this would be my solution of choice. Don't ask me about
implementation though.
Changing the key already sent to key servers and several people from my
address book doesn't sound very appealing to me either. Perhaps you'll
beg to differ, but in my opinion an application like GPA should work out
of the box, no matter which encoding.

I've used

$ CFLAGS="-O0 -g -O2 -march=pentium4 -fomit-frame-pointer" ./configure \
  --prefix=/my/path

to configure, compiled GPA and ran it inside the debugger. Here's what
it said:
