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:

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

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.

Any idea what might be causing this and how to fix it (if possible)?
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.
