Using special characters in filenames is a very bad idea. You risk losing data. Ocaml is but a single example of non-Unicode aware software.
(1) I've encountered several files where Mp3Packer messes up non-mp3 data at the end (APETAGEX/ID3). How non-standard non-fb9 the APETAGEX might be, this should not happen. Here is one sample processed with v1.17, it has happened before with other versions. It would seem that mp3packer chokes on the repeated "ALBUM" for some reason. Copy the code blocks to notepad in order to view them properly.

(2) How about setting the process priority to low by default? The processing with Z takes a long time and the comp becomes pretty much unresponsive during this process.
