Hi Philippe,
thanks for getting back to me so quickly! And sorry for not providing all the details right away.
I'm using Git 2.30.0.windows.1 (I believe that's the latest), gpg 2.2.27 (installed via gpg4win 3.1.15), and PowerShell 7.1.1. You might have seen my second email to the list in which I described that setting the OutputEncoding in PowerShell to UTF-8 fixed at least the display of the é (and probably all other umlauts and special printable characters). The signature output from git show --show-signatur is still printing the ^M carriage return character at the end of each line:
commit 69022a47744fcb3801572ac5d14295bcab274295 (HEAD -> master)

Since git verify-commit does not have those carriage return characters, I'm still wondering where they might come from.
Cheers,
René

What Git and GPG versions are you running ? And what Powershell version (I don't think that matters but still, a complete environment description usually goes a long way).
Can you come up with a reproducible example ? (Complete steps starting with 'git init' and 'gpg --gen-key')
Cheers,
Philippe.
