Hi! Could you add a test to test/language.test.tsx?

[seanghay]

Hi @shuding! I've added the test now.

[shuding]

Thanks! It seems that the characters are not rendering on the playground, I'll invest why.

@shuding
Khmer text is now rendering, but it's not correct. Khmer characters has font ligatures. I'm not sure how to fix it. It seems to be a problem with opentype.js?

Characters: ស + ួ + ស + ្ + ដ + ី + !
Text: សួស្ដី!

on https://opentype.js.org/

Btw node-canvas renders Khmer text perfectly fine. Here is an example https://github.com/seanghay/node-canvas-khmer

It looks like node-canvas is using pango layout engine.

Yeah, we don't have ligature (and some other features) and I'm not sure if that's a missing thing in opentype.js or it's a bug. Worth to look into it.

Someone released an another engine which supports Khmer language and many others.
