Japanese characters do not render under some circumstances
Japanese characters usually do not render.
I can reproduce this issue by:
- going to the Wikipedia page for the katakana Unicode block.
- going to any YouTube comment with Japanese text.
- hovering over the screenshot of the YouTube comment so that the tooltip containing the name of the file is shown.
On YouTube the text renders only if 1.27916663885116563rem <= font-size <= 1.92083328962326036rem. Increasing `gfx.font_rendering.fontconfig.max_generic_substitutions` from 3 to 99 allows some punctuation to render and makes the text take up horizontal space. Further increase of the value to 999 causes the interpunct to render in the Wikipedia page.

I believe this was caused by missing fonts. I did not originally realize this as I expected fonts to be supplied by the server, and programs usually display a "missing character" character when no available fonts have a character, which did not occur here.
I resolved this by changing my system configuration as follows: nix``` fonts = {
packages = with pkgs; [ google-fonts ];
}; ```

When I hover over the link to the Wikipedia page for the interpunct the %E3%83%BB does not render.
My problem may be the same. Titles of Japanese youtube videos show garbage characters and the comments are garbage characters, too.
I use macOS 15.5 and Firefox 140.0.4 (aarch64). The main language of macOS is English. I don't log in to Youtube.
