In a LKRG source code file a comment includes a real name which contains this sign: ł
Non-malicious.
This triggers to dm-check-unicode check.
Therefore excluding the files where this happens from the check.
This is clearly a non-ideal solution but fixing this is an issue for whole Free and Open Source community. See also Detecting Malicious Unicode in Source Code and Pull Requests
