2.11.1 breaks log output for non-ASCII characters (e.g. German Umlauts)

[Snaptags]

• [ X ] I was not able to find an open or closed issue matching what I'm seeing

Setup

• Which version of Git for Windows are you using? 64-bit

$ git --version --build-options
git version 2.11.1.windows.1
built from commit: 1c1842bcba45569a84112ec64f72b08eb2d57c68
sizeof-long: 4
machine: x86_64

• Which version of Windows are you running? 8.1 64-bit?

$ cmd.exe /c ver
Microsoft Windows [Version 6.3.9600]

• What options did you set as part of the installation? Or did you choose the
  defaults?

Path Option: Cmd
SSH Option: OpenSSH
CRLF Option: CRLFCommitAsIs
Bash Terminal Option: MinTTY
Performance Tweaks FSCache: Enabled
Use Credential Manager: Enabled
Enable Symlinks: Enabled
Enable Builtin Difftool: Disabled
(same as in 2.11.0)

• Any other interesting things about your environment that might be related
  to the issue you're seeing?

German Windows

gitconfig contains

[i18n]
	logoutputencoding = Windows-1252

which used to work in 2.11.0 and does not in 2.11.1

Details

• Which terminal/shell are you running Git from? e.g Bash/CMD/PowerShell/other

PowerShell

• What commands did you run to trigger this issue? If you can provide a
  Minimal, Complete, and Verifiable example
  this will help us understand the issue.

git log --oneline

• What did you expect to occur after running these commands?

• What actually happened instead?

• If the problem was occurring with a specific repository, can you provide the
  URL to that repository to help us with testing?

git init
echo "testfile" > bääää.txt
git add .
git commit -m "aä oö uü sß - all broken now"
git log --oneline --stat

I believe Issue #945 and its compatriots covers this. the latest prerelease includes a fix. https://github.com/git-for-windows/git/releases/tag/v2.11.1.windows-prerelease.2 (the sort order on the release page doesn't quite get it right ;-)

Also check for your LC settings.

[Snaptags]

No, not really. The prerelease behaves exactly like the release
git version 2.11.1.windows.prerelease.2
built from commit: 86d49cc
sizeof-long: 4
machine: x86_64

Tried to set LC_ALL=C, does not make any difference either

[Snaptags]

Tried some older versions, the issue must have been introduced somewhere between
git version 2.11.0.windows.1 (does not print a commit id) and
git version 2.11.0.windows.2 (not working any more)
built from commit: 9e46438

Note beyond: maybe the file name output never worked correctly, did not notice that, because we don't use non-ascii characters for file names :-)

[kgybels]

@Snaptags Try export LC_ALL=de_DE. Also make sure your logoutputencoding, your locale settings and mintty text settings (set Options->Text->Character set to CP1252) all match.

[Snaptags]

Setting an environment variable LC_ALL with content de_DE seems to fix the issue, thanks a lot!

[kgybels]

@Snaptags That's good news! If you want to see your paths as well, try git config core.quotepath off, characters outside the ASCII range get quoted by default.

[Snaptags]

That's just differently wrong :-)
But I hardly have any file names with non ASCII-characters, so I don't care :-)

[kgybels]

Ah, yes, of course, the path is UTF-8 and you're using Windows-1252 for text. Nevermind then :)

[Snaptags]

Went back to LC_ALL=C. Better to have ugly git logs than MILLIONS of Perl warnings about how the locale could not be set.

[Snaptags]

adding --encoding to the log call is a partly solution. It doesn't really matter WHAT you set the encoding to, actually. Very strange:
git log --oneline --stat --encoding=wtf
