MIKMIDIMetaLyricEvent with Accents or "ñ" in the String value become Null

[inertlab]

This may be happening with other special characters but so far I've noticed events with accents nullified. Events with é í á ó ñ anywhere in the the string have a String value of Null

example:
this is what i get
<MIKMIDIMetaLyricEvent: 0x6000002ea260> Timestamp: 24.833333 Type: 21, Metadata Type: 0x05, String: (null)
this is what it should have been
<MIKMIDIMetaLyricEvent: 0x6000002ea260> Timestamp: 24.833333 Type: 21, Metadata Type: 0x05, String: acabó

if I edit the ó in the midi file, then the full string shows up.
