I agree, but that implies that this is not an item to standardize, because if we standardize, authors would expect it to work without knowing what Unicode composition is. I think that is the point @behdad and @litherum pointed out.

Still happy to keep discussing requirements, and I think all impls try to improve where technically possible is a good thing. I filed Blink tracking bug at [crbug.com/905603](http://crbug.com/905603).

A question remains. If it's not reliable, what authors can do. I think one option is to always use web font as suggested before. The other is to use graphics instead, such as SVG, though it may not be possible depends on use cases. When I discussed similar requirements for East Asian in EPUB, mostly in educational ([ex1](http://keyakizaka46labo.com/wp-content/uploads/2015/09/f8b410ce15756599ae4b7ce5880ac992.png) [ex2](https://i2.wp.com/help-kaigo.com/wp-content/uploads/2017/04/1.書き順.jpg?ssl=1)), it was so impossible that it was easy to conclude this must be a graphics.

Arabic or Devanagari are probably possible given the current font implementations, so they could have a choice.
