With some tracks from behind the decode_kirillis plugin, the MusicBrainz Picard program crashes. With a sufficiently large library, it is quite difficult to find a track due to which an error occurs.

The error occurs in the 64th line of the decode_cyrillic.py plugin code.
Sometimes it causes a UnicodeDecodeError that is not intercepted (not to be confused with UnicodeEncodeError). This exception crashes the entire program MusicBrainz Picard.

One solution is change 65 line:

except UnicodeEncodeError:

to:

except UnicodeError:

I add an attachment - the track on which such an error appears. When it is processed, the program crashes.

I did not find any contacts of the author of the plugin, so I am writing to you, maybe you want to correct the error.
