For example, `File' is showed as "address@hidden(F)" (left most item on menu).
It should be shown  as U+30d5 U+30a1 U+30a4 U+30eb 
(Fu A-Small I Ru, in Katakana) and "(F)".

$ perl -e 'print "\x30\xd5\x30\xa1\x30\xa4\x30\xeb"' | iconv -f ucs-2 -t sjis | 
hexdump -C
00000000  83 74 83 40 83 43 83 8b                           |address@hidden|

On Japanese Windows, strings should be written in CP932 (or Unicode),
but lilypond does not.
