>There isn't actually a reason you'd want U+76F4

The fact that it was the only one that properly rendered for me is an actual reason.

And just think, that will be true about half the time!

You don't want U+76F4, you want buggy Asian fonts to be fixed.

(On second thought... did it render correctly for you? Did you check?)

Every single time I reload the page the other characters are a broken rectangle, so experimentally it's 100% of the time I'll need that character. What I want is to not see a broken rectangle. One can't say that U+76F4 is useless when it clearly is serving a use for my computer.

OP means it's the only one that renders at all. It could be wrong but the other two are just missing-glyph boxes which are definitely wrong. Those code points appear unusable as a practical matter.

On default modern Android I get the same: Only U+76F4 renders, not the other two.
