Failed to lunch Menulibre in the presence of entries with invalid names

I installed an app under non-utf8 locale. Some of its non-utf8 encoded/named menu entry files stopped Menulibre from being lunched.

I am using Menulibre 2.2.0. I think I have located the bug:

"menulibre/util.py" -> "determine_bad_desktop_files" -> "for line in result.stderr.decode().split('\n')"

where "result.stderr" may not always be decodable.
