The fonts in Text.font_list() cannot be loaded in Windows

[KeJunMao]

Description of bug / unexpected behavior

The fonts in Text.font_list() cannot be loaded in Windows

I tried installing the same fonts in Docker and running it, and found that they could be loaded normally.

A potentially helpful link:

https://discourse.gnome.org/t/why-does-pango-on-windows-fail-to-open-some-fonts/15967

Expected behavior

The fonts can be loaded correctly in Windows

How to reproduce the issue

Code for reproducing the problem

Test font: https://github.com/atelier-anchor/smiley-sans

from manim import *

class FontScene(Scene):
    def construct(self):
        text = Text("你好，Hello", font="Smiley Sans")
        print(text.font_list())
        self.add(text)
        self.wait()
