Hello,
first, thanks very much for the fast answers from Geoff and Pedro!
I make a MIDI player Karaoke-App which shows the lyrics (see attached image).
As the API wich I use in XCODE does not deliver Meta events, I extract the Lyrics before I start playing the MIDI file.
Everything is working fine, except the wrong characters for e.g. in Chinese MIDI files.
Here some additional informations:
Adding lyric text with program "Logic", shows the same effect:
The Unicode Bytes in the MIDI file does not correspond to the Chinese lyric characters, so it must be some encoding done.
What is the specification of the "Bytes before unicode" (e.g. "e7"

?
Where can I find a conversion table?
MIDI file downloaded from:
http://www.karaokeden.com/karaoke/lyrics/Chinese/11.kar
Original lyric in MIDI file Byte before unicode
燭羲斕扂崋臘忔 뺲隕覂뒋릫뾔薕
71 ED be b2 e7
7F B2 96 95 e6
65 95 89 82 e6
62 42 b4 8b e5
5D 0B b9 ab e7
81 D8 bf 94 e5
5F D4 85 95 e8
Note: The MIDI file "11.kar" seems to be corrupt, as the "FF 2F 00" at the end is not complete (only "FF 2F"

.
After adding the missing Byte "00", the MIDI file plays correctly with the Apple API "MusicPlayer" in XCODE.
Thanks for helping and best regards
Walter
