As long as your code correctly handles bytes in the range from 0x20
to 0xFC then it should work fine with Japanese (Shift-JIS) as well.
If I was going to hazard a guess, it would be that the algorithm has
a problem with sign-extension, such that English user names with
characters in the high-ASCII range would also fail.
