If this is a platform-specific problem, can you please:
- send your midi file for comparison (mine is attached)
- test whether UTF-8 characters are handled properly during conversion
(I initially thought the problem was in non-ascii characters, but then
I removed the non-ascii ones and the problem persisted)

Is there any good "midi viewer" around?
