ANSI Color Code bug in Windows

[Rickaym]

Description of bug / unexpected behavior

ANSI Control code formatting for tracebacks and logs in manim seems to be corrupted when opened with command prompt or Powershell (manim version 0.11.0 and 0.12.0)

Expected behavior

Well the traceback should be formatted properly.

How to reproduce the issue

Any manim scene file works.

from manim import *

class SomeRandomText(Scene):
    def construct(self):
        text = MathTex(r"\mathbb{R}", fill_color="#FFFFFF").scale(4)
        self.play(Create(text))

manim -pql source.py -a

Additional comments

In my estimation, this issue is caused by the ANSI Terminal Control support which was added to the Windows 10 console host in build 16257 (and later) being disabled by default.

By using os.system(""), the ANSI support gets enabled as per here.

As you can see, the Manim Community ←[32mv0.←[0m←[32m12.0←[0m gets printed with invalid formatting, and right after I executed the echo the formatting returns to normal.

from manim import *
from os import system

print("ENABLING ANSI")
system("")

class SomeRandomText(Scene):
    def construct(self):
        text = MathTex(r"\mathbb{R}", fill_color="#FFFFFF").scale(4)
        self.play(Create(text))

Is this fixed for you now on manim v0.15.0

Unfortunately, not.

That's unfortunate :( Do you have a fix in mind?

[behackl]

Maybe an upgrade of rich would help; we should check whether they have any corresponding issues / PRs in their library repo.
