That looks like an ugly hack.  Where do you store the table?  If you
have to store a table somehwere in a header-packet, you could do a
better job by storing entropy-information in it and huffman-decoding
subtitles into UCS codes.  Anyway, subtitles shouldn't pose such a
bitrate-problem, no?

As someone who frequently works with multibyte character-sets, I just
want to emphasize how important unicode (whether UTF-8, -16, UCS or
whatever) is.  People tend to forget that there are non-european
languages, and even for european languages, the chaos crated by
ISO-8859-1 up to ISO-8859-15 is extremely problematic.


PS:  I didn't know that elvish is now part of unicode ;-)
