git log output encoding issues on Windows 10 command prompt

Okay, I experimented a bit and found out that Windows Git commands actually need UNIX variables like LC_ALL in order to display Polish (or other UTF-8 characters) correctly. Just try this command:

set LC_ALL=C.UTF-8

Then enjoy the result. Here is what happened on my console (font "Consolas", no chcp necessary):

---

Update:

• Well, in order for Windows commands like type (display file on console) to work correctly, you do need chcp 65001.
• And if you prefer commands from Git Bash like cat you profit from the aforementioned set LC_ALL=C.UTF-8.

Update 2: How to make the changes permanent

As user mono blaine said, create an environment variable LC_ALL and assign it the value C.UTF-8, either globally or for your own user profile only (sorry for the German screenshot):

Next time you open a command processor console (cmd.exe) you should see the variable value when issuing the command echo %LC_ALL%. In PowerShell you should see it when issuing $env:LC_ALL.

The simplest way to make the UTF-8 code page permanent ist to open regeedit and add a new value named Autorun of type string to section HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor and assign it the value chcp 65001.

Henceforth, this command will be executed each time you open a new cmd.exe console. You even see its output in the new window: "Aktive Codepage: 65001." (or similar in your respective language).

Oh, by the way: In order to display a UTF-8 encoded file correctly in PowerShell you can use Get-Content -encoding UTF8 file.txt or cat -encoding UTF8 file.txt (cat being an alias for Get-Content in PowerShell).

If anyone is interested in the PowerShell equivalent of set LC_ALL=C.UTF-8, that is:

$env:LC_ALL='C.UTF-8'

However this works only for the current session. To make it permanent, two possibilities:

• create an environment variable named LC_ALL with the value C.UTF-8
• or put $env:LC_ALL='C.UTF-8' in your $Profile file

I am using Git via Powershell Core v7.0.3 with posh-git installed inside Windows Terminal on Windows 10.

I have been browsing through answers and tried many of them. The solutions that worked for me were:

• Change a Git setting: git config --global core.pager 'less --raw-control-chars'
• Add $env:LC_ALL = 'C.UTF-8' to the current Powershell profile

These solutions both work separately. I chose to use the Git command as the problem seems to be related to Git, and Powershell profile stays cleaner.
