RE: Git Commit Signature Encoding

Hi all,

I'm trying to fix an encoding (?) issue when viewing gpg signatures for commits in PowerShell Core on Windows. Apparently, git changes the output from gpg depending on the command used. Here's what I see:

git show --show-signature
This command shows strange line endings and is unable to properly display the é in my name:

commit d7a43da0bd3bc7e31dd46afb8ccd78735ba43a36 (HEAD -> master)
gpg: Signature made 26.01.2021 15:28:26 W. Europe Standard Time^M
gpg:                using RSA key 3848D5B2A3D45419D7F564F97802B995CDB4A2EF^M
gpg: Good signature from "Ren<82> Schumacher [off-list ref]" [ultimate]^M
gpg:                 aka "Ren<82> Schumacher [off-list ref]" [ultimate]^M
Author: René Schumacher [off-list ref]
Date:   Tue Jan 26 15:28:26 2021 +0100

    Commit with signature

git verify-commit
This command does not show the line endings but still fails to properly show the é:

gpg: Signature made 26.01.2021 15:28:26 W. Europe Standard Time
gpg:                using RSA key 3848D5B2A3D45419D7F564F97802B995CDB4A2EF
gpg: Good signature from "Ren82 Schumacher [off-list ref]" [ultimate]
gpg:                 aka "Ren82 Schumacher [off-list ref]" [ultimate]


git verify-commit --raw
This command does properly show the é in my name so I guess that gpg output is correct and there's something happening while git parses the gpg output:

I already set the environment variable LC_ALL to C.UTF-8, which fixed the commit message output (see first screenshot) but unfortunately not the signature output. Any idea what might be causing this and how to fix it (if possible)?
