This is _only_ an issue on Windows, and it is several issues.
1) the maximum command-line length on Windows i rather small (though i
somewhat doubt that is an issue.
2) Windows designers thought it intelligent to use UTF-16 (UCS-2
orignally), thus those Japanese characters can not be passed to MPlayer
via the normal main() arguments but you must call a special function.
Since MPlayer cannot and will not use UTF-16 internally, you'd then have
to convert them to UTF-8.
3) Then the same issue exists with the file-open functions, you can not
use UTF-8 there, thus you can not use the same functions, so you have to
use different functions to open the files in any place where you want to
support non-ASCII.
4) In order to avoid all that mess which is somewhat hard to implement
in MPlayer cleanly (though mostly the problem is that nobody cares), I
think SMPlayer might try to use the short (8.3) name. This has two
issues: subtitles are not found, since their short name does not relate
exactly to the short name of the movie, plus I think Vista no longer
creates short names by default.
