Cool!

Any special reason to use a comma between the locale and the encoding,
instead of a dot? Not only does the list (at first glance) now look
comma-seperated, almost everywhere a '.' (dot) is used to glue the
encoding to the locale...

Maybe we could even take this one step further and use IMAGE_LINGUAS
and introduce an IMAGE_ENCODINGS and combine these together to get a
list of binary locales to generate?
