r12a has just created a new issue for
https://github.com/w3c/typography:
== How are underlines positioned in non-Latin text? ==
CSS WG folks and browser implementers are looking for information
about how to position underlines for various scripts. Can anyone
provide them with the information they need for one or more scripts?
See w3c/csswg-drafts#459 (comment)

Hi Uma,
I just finish installing MS.Word 2016 into my MacBook.
On top of below note,
I attach some screen shot from latest MS.Word 2016.
Here's what I talk about, a correct way to make underline Thai text.
Hi Uma,
If I'm not mistaken, they want to introduce "offset" attribute to shift
the position of the underline.
If that's the case, it'd be no use for Thai.
Because Thai script require underline to be exactly in "under" level of
rendering which is the typical rendering of underline position.
The thing is, when there is a colliding between underline and the glyph,
the underline must be absent only where the colliding occur with some
small surrounding white space.
Unfortunately, there's nobody implementing that for a while.
>From What I can check as of now, even MS.Word 2013 has colliding underline
with Thai glyph.
