One thing to keep in mind when developing these large lists of fonts is that they are generally terrible for performance if the appropriate glyphs for what you are trying to display aren't present in the first font (and the font is available - this isn't an issue if the font isn't available at all).

This is generally more of an issue with non-latin scripts (or when emoji is present for example), and developers adding a font which doesn't have glyph coverage - or sparse glyph coverage.

Chrome/Firefox devtools both have a section "Rendered Fonts"/"Used Fonts" which show which gylphs are used from which font.

Additionally if you are showing non-latin, make sure to language tag your markup: https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/...

`font-family: sans-serif` if not language tagged with incur a similar fallback perfromance penalty (the browser will have to change the "english" sans-serif font, find no glyphs, then use the "other-lang" sans-serfic font).
