Without implementing something like UniversalDetector is hard to guess the correct option. In this case it is UTF-8, like in the case of #577. I can probably set UTF-8 as the selected option (even try it by default) if the decoding worked.

Anyway I still don't understand why some developers keep adding resources with characters on some filenames that may break the integrity of the code signature.

It's crazy, of course most of them remain hidden from our eyes in the app bundles.
