    .. manim:: TextMoreCustomization

                    self.add(text1)

    As :class:`Text` uses Pango to render text, rendering non-English
    characters is easily possible:

                morning = Text("வணக்கம்", font="sans-serif")
                chin = Text(

Review comment (suggestion):
Use double quotes everywhere and don't mix, it doesn't look good.
