[Git Bash] Impossible to run a bash script from Windows Explorer if the path/name contains non-ASCII characters

[TestPolygon]

Description

I cannot properly run the .sh script by clicking on it if the path to the script contains non-ASCII character(s). The script does not work at all (I see only immediately closing of a console.).

I have Windows 10, 64-bit, Git-2.21.0 64-bit.

For example:
The content of the script:

#!/bin/bash
echo "Hello there!"
sleep 3

I can properly run the script in the console (git-bash.exe) in any way.

But, if I run the script from the Windows' Explorer by double-clicking on it:

• If the path contains only ASCII characters: everything is OK.
• If the path contains any non-ASCII character: the script (the console) closes immediately after the start, the script does not do any work.

Examples of the pathes:
Good:

• C:\script.sh
• C:\#Bash\New folder\script.sh
• C:\#Bash\Pokmon.sh

"Bad":

• C:\#Bash\Pokémon.sh Diacritic
• C:\#Bash\Catálogo\script.sh ES
• C:\#Bash\Новая папка\script.sh RU
• C:\#Bash\New folder\脚本.sh ZN
• C:\#Bash\Surrogate Pair 💧\script.sh Emoji

I would like to be able to run scripts by double-clicking if the path contains non-ASCII characters, at least characters from BMP (Basic Multilingual Plane).

Probably the place to start looking is the install scripts in the build-extra repo to see how the 'double clicking' is set up. I couldn't tell (personal ignorance ;-) if you are using the default windows mechanism for file associations etc to get the script to run, or if it was via a Git for Windows specific action mechanism (a right click option).

As a guess you are getting some character conversion issue between all the different apps/OSes/layers, such that you have, say, a windows characters being passed as if it is utf-8 or some such confusion.

Steps to reproduce

1. You need Windows (I think any 10, 8, 7). Windows (NTFS) uses UTF-16 for file, directory naming.
2. Create a bash script
3. Install git (git-bash included) the latest or not version from the site (I use the default settings during installation)
4. After installation, you can run the script from Windows Explorer
5. If the path to the script (or the name of the bash script) contains non-ASCII characters it will not work.

I can run the script from the console in any case:
If the script is located in C:\#Bash\New Folder\💧\ and its name is water 💧.sh:
I can open git-bash.exe here using the context menu and run the script (even if the name of the script contains non-ASCII chars). It works.

User@User-PC MINGW64 /c/#Bash/New Folder/рџ’§                                                    
$ ./water\ ^Xрџ’§.sh
Hello there!

I see a little not presentable view of the output of the console, but the script works.
For name typing I use auto-complete (tab).

Another example:
Path: C:\#Bash\New Folder\Catálogo
Script: hello.sh
The console output:

User@User-PC MINGW64 /c/#Bash/New Folder/CatГЎlogo
$ ./hello.sh
Hello there!

The ability to run bash scripts from Windows' Explorer is very useful and convenient. In this case, a bash script behaves like a normal program(an .exe file). This is especially useful when you use the drag and drop mechanism to pass arguments to the script.

@TestPolygon sorry for the long wait. This should be fixed in the next version of Git for Windows. To make sure, please download the 64-bit package from https://dev.azure.com/johannes-schindelin/git/_build/results?buildId=4912&view=artifacts, unpack usr\bin\msys-2.0.dll into your C:\Program Files\Git (this should overwrite an existing file, you might want to back it up in case of unforeseen complications).

drive.google.com, dropbox.com, mega.nz or any other file sharing service?

@dscho that link requires a microsoft login. The download is probably only accessible to you.

Well, boo.

In the meantime, it made it into the Git for Windows SDK. Try this: https://github.com/git-for-windows/git-sdk-64/raw/master/usr/bin/msys-2.0.dll

There also has been a new snapshot in the meantime, if it is easier for you to run the Git for Windows installer.

Running by double click works well now, but by drag and drop does not work well.

How to reproduce

1. Use the bash script with the follow code:

#!/bin/bash

# Shows args count
args_count=$#
echo "Args count: $args_count"

# List of sorted args
printf "%s\n" "$(printf "%s\n" "$@" | sort -n)"

sleep 2

2. Drag and drop any file on this .sh file.

If the bash script has "bad" character(s)* in its name or/and path, the script does not work at all when you drag and drop file(s) on it.

When only the files (that you drag and drop on the script) have "bad" character(s) in its name or/and path it seems to work.

I tried this with https://wingit.blob.core.windows.net/files/Git-prerelease-2.24.0.windows.2.14.g8715ee2266-64-bit.exe and it worked for me with the file name ähm.sh... but yes, I can reproduce with the "name" you provided.

Not sure when I will get to debug this, though.
