So why isn't the English/US-ASCII bias for msgids considered a liability
for gettext?  Do non-English programmers not want to use native literals
in their source code?

If we adhere to this limitation instead of extending gettext then it
seems like Zope will be forced to use something else, and that seems
like a waste.  Its msgids come from sources other than program source
code and such sources may indeed be written in non-English.  It seems
like gettext is so close and all the machinery is almost there, that
this small enhancement should be harmless and helpful.

BTW, I believe that if all your msgids /are/ us-ascii, you should be
able to ignore this change and have it works backwards compatibly.

Also, this change ought to visibly only affect .ugettext() which isn't
part of the traditional gettext API anyway.

Isn't this just another validation step to run on the .po files?  There
are already several ways translators can (and do!) make mistakes, so we
already have to validate the files anyway.
