Non-Western fonts cannot align Western fonts and formulas

[TXFK]

As the picture showed, Non-Western(Chinese, Japanese, for example) fonts cannot align Western fonts and formulas.

Here is the code:

from manimlib import *
class Example(Scene):
    def construct(self):
        self.play(
            Write(
                MTexText("勾股定理 Pythagorean theorem のぬ $a^2+b^2=c^2$")
            )
        )
