[BUG] Colors doesn't work on Git Bash

[naveen521kk]

Describe the bug
I am Windows 7 and install python 3.8 where I used Git Bash(For a change.). I typed the following things in terminal where it should show the image as in ReadMe.
While I get a long error Message of UnicodeEncodeError
The output I get is

              Colors 256 colors or 16.7 million colors (if supported by your
                     terminal).

and no colours in it.

Also, when I run py -m rich.logging
I get a ZeroDivisionError.

*** You may need to add PYTHONIOENCODING=utf-8 to your environment ***

Btw, everything is fine with CMD or Powershell.

To Reproduce
Running py -m rich in Git Bash For Windows shows these errors.

Platform
I am on Windows 7. The terminal I am using is Git bash. The rich version is rich==8.0.0

[willmcgugan]

You are missing some environment variables that set the locale.

Try the following:

export LANG=en_US.UTF-8 
python -m rich

Or

PYTHONIOENCODING=utf-8 python -m rich

Ok now that render's fully but now it misses colour.

[willmcgugan]

What is your TERM env var set to?

echo $TERM
echo $COLORTERM

Does this give you None?

from rich.console import Console
console = Console()
print(repr(console.color_system))

[naveen521kk]

$ echo $TERM
xterm
$ echo $COLORTERM

The below one gives me None.

from rich.console import Console
console = Console()
print(repr(console.color_system))

[willmcgugan]

How about this?

echo $NO_COLOR

and this...

print(console.is_terminal)

[naveen521kk]

$ echo $NO_COLOR

The second one is False.

[willmcgugan]

If "is_terminal" is False it means that git bash isn't a real terminal, and Rich is defaulting to text without color.

You can force Rich to bypass terminal detection with the following:

console = Console(force_terminal=True)
console.print("[bold blue]Color")

I don't know much about git bash, but it looks like it is emulated and not a full terminal.

[naveen521kk]

I got colour working with Poetry.(While colour doesn't work on cmd nor PowerShell but works in Git bash.) It uses Pastel. I think Git Bash is very similar to bash but I really don't know about it much.

[naveen521kk]

Update: Trying the same on Msys2 MINGW32 bash shell I got the coloured output but it looks worse with tables.

There all the things came as in git bash except the last one

print(console.is_terminal)

^ returned True.

[willmcgugan]

It looks like it doesn't support unicode characters as used by the table borders. You should use box.ASCII when rendering tables.
