[windows]: Any Theme with Git-Bash is causing an overlap of text

[Ayanrocks]

While using GitBash 2.50.windows.1, any theme when used is causing a overlap of text character.

The issue most likely be for messing up the PS1 variable but these are default themes like font, agnoster etc.

When setting the theme="" then overlap issue doesn't seem to work.

This overlap mainly happens when scrolling through history of commands using the up arrow

Any help as I'm not able to find any similar issue and has been facing this problem for quite some time

Terminal: Windows Terminal latest Windows: Windows 11 font: Jetbrains Mono NL

This typically happens when the character width schemes assumed by Bash and the terminal differ. In particular, it is likely that emojis or ambiguous-width characters are related. Which terminal do you use? I checked the behavior in my environment with the default terminal (mintty) of Git Bash, but the problem doesn't reproduce.

Yeah I assumed that as well but I'm unable to fix it. Its happening in all my terminals. Current one is Windows Terminal Latest as per the SS. But I tried in Tabby, Vscode as well, Even in Warp.

Then, it might be on Bash's side. Bash uses Readline for line editing, and I think Readline uses the system's wcwidth, which is affected by the current locale. What is your current locale?

$ locale

This was the output when trying the above command

ayanb@IN-9NOMWL4:~/Developer$ locale
LANG=
LC_CTYPE="C.UTF-8"
LC_NUMERIC="C.UTF-8"
LC_TIME="C.UTF-8"
LC_COLLATE="C.UTF-8"
LC_MONETARY="C.UTF-8"
LC_MESSAGES="C.UTF-8"
LC_ALL=

Thank you for the information. Mine is this:

$ locale
LANG=
LC_CTYPE="ja_JP.UTF-8"
LC_NUMERIC="C.UTF-8"
LC_TIME="C.UTF-8"
LC_COLLATE="C.UTF-8"
LC_MONETARY="C.UTF-8"
LC_MESSAGES="C.UTF-8"
LC_ALL=

I tried changing all locale categories to be C.UTF-8, but the problem still doesn't reproduce in my environment with mintty. I also tried Windows Terminal, but the problem still doesn't seem to reproduce.

I also downloaded and installed "JetBrains Mono NL" and specified it in the Windows Terminal settings, but the problem still doesn't reproduce.

I'll think about other possibilities later. Do you have any other special settings in your ~/.bashrc?

This is my .bashrc File.

Also point of observation. Setting the LANG to en_GB.utf-8 seemed to be working, but if it's not set for you and it's still working for you then there must be some other bug. Can you tell me how the LANG is being set in your case?

[akinomyoga]

OK, thank you for the information. In my case, LANG is unset by default.

$ declare -p LANG
bash: declare: LANG: not found

In my environment, the problem doesn't reproduce regardless of whether LANG is unset or set to ja_JP.UTF-8 or en_GB.UTF-8. Maybe another possibility could be the language of the Windows system. I'm using Windows with the Japanese language. The base system of Git Bash is based on MSYS2, and MSYS2 is a fork of Cygwin. In the past, I faced with a strange behavior in Cygwin, which only happened under the Windows systems with specific languages. I think the problem at that time was unrelated to the present problem, but I think it suggests a possibility that other behaviors of the MSYS2 system may depend on the language of the Windows system.
