Git Tips and Tricks
Display unquote non-ascii in git bash
Git quotes any non-ascii character by default, not only asian ones. There's an option to disable this quoting behavior.
You can disable it using the following command:
git config --global core.quotepath false
Or, alternatively, by adding the following snippet to your git config file ($HOME/.gitconfig usually)
[core] quotepath = false
After this, git should show your filenames exactly as they are.
