But I don't think you'd ever want to do that.  In fact, I think in
general you're probably talking about ascii msgids or utf-8 encoded
Unicode msgids.  I'm not sure what else would make sense.

Didn't even know about msgunfmt. :)

Right, but see above.  E.g. if your string literals are all Spanish and
you want a Turkish translation, then utf-8 is the only common encoding
you could possibly use in a .po file, right?

Yep, although it would be easy for the extractor to add a charset=utf-8
to the pot file.

Is this still a problem for when charset=utf-8?
