Unicode supportr for fleet names please

It would be nice to be able to use Japanese and Chinese when renaming fleets.

The fonts would need to also support those languages, and unfortunately those are only ASCII fonts.  Given the nature of fonts in games, it's not really possible for us to have the entire unicode set as that would make the fonts prohibitively large, and most fonts that are sci-fi themed don't have unicode support to begin with.
