Speaking of Asian fonts, does anyone know of CJK character sets that can be loaded via CDN à la Google Fonts -- for example, Google's Noto CJK Simplified Chinese fonts?
I don't think there's a good solution to CJK web fonts yet. If one existed, I think it would need to involve a font rendering technology where character shapes can be generated from strokes and radicals, instead of the literal shape of every character having to appear separately in the font.
Do you perchance mean "dynamically loaded, on demand"? Because there's no standard for it. Because – as usual – "good enough for Western audiences".
But maybe that's not enough of a benefit unless there's also a way to say "okay you need to use this radical, but a bit narrower, but the strokes need to be the same width and not distorted".
