Purpose

I want to include CJK characters in my figure name

The text inside control UI menu was messed up

Current workaround

I did set font for pygfx to enforce it render CJK with a local font file

from pygfx.utils.text import font_manager, FontProps

font = font_manager.add_font_file(
    "fonts/fusion-pixel-12px-proportional-zh_hans.ttf"
)
font_manager._default_font_props = FontProps(
    font.family,
    style="normal",
    weight="regular",
)

But looking into the source code, I think I cannot set default font for ImGui similarly, it must be passed to Figure.__init__
