I've not seen it myself, but I'm sure we can add the "--from-code=UTF-8"
option to "*/po/Makevars.template" or "*/po/Makevars" if that helps.

I'm actually not sure if it needs to go in */po/Makevars, or whether
that is a generated file. It _seems_ that Makevars.template (counter-
intuitively) is the generated file.

If someone would like to work up a patch against GIT HEAD, I'll give it
a cursory test and push it.

I don't have the time right now to do it myself.

Best wishes,

Peter C.
