over in https://bugs.debian.org/855419, Witold Baryluk writes that with locale
pl_PL.UTF-8 , gpg --gen-key gets stuck on the "Change (N)ame, (E)mail, or
(O)kay/(Q)uit?" prompt -- no entry seems to have an effect.
I've tried this myself, enabling the pl_PL.UTF-8 locale systemwide (but not
making it the default locale), and running:
LC_ALL=pl_PL.UTF-8 gpg --gen-key
I note that "w" at the prompt causes the process to quit with:
gpg: Procedura generacji klucza została anulowana.
and a return code of 2.
