unexpected NULL character during export

I converted MuseScore_General.sf3 to .sfz with polyphone. This is the default sound bank of MuseScore3.

I want to open it with sforzando but it cannot parse the sf2 file. The reason: end of comment section is followed by a NULL byte, comment00 0A 0A<group
So I have to remove NULL to solve this issue. In other words, comment0A 0A<group works well.

If I delete the last character from the comment in polyphone editor, it exports the content well.

(I guess you converted sf3 to sf2 (not sfz) with Polyphone?)

You should address the sf2 parse error to sforzando. Here a an extract of sf2 format specification:

5.10 The ICMT Sub-chunk
The ICMT sub-chunk is an optional sub-chunk containing any comments associated with the SoundFont compatible bank. It contains an ASCII string of 65,536 or fewer bytes including one or two terminators of value zero, so as to make the total byte count even.
