Suggestions to the gap analysis #179

Closed xfq closed 6 years ago

xfq commented 6 years ago

Here are some suggestions to the gap analysis document. Any further comment is welcome!

Fonts:

I propose changing it from tbd to advanced.

One issue we might want to mention is that font matching/fallback for variation sequences is not implemented correctly: https://github.com/w3c/csswg-drafts/issues/1710

Ruby annotation:

Mention the lack of support of Bopomofo ruby and difficulties selecting ruby text.

Text decoration:

Punctuations should be skipped by default for emphasis marks.

Emphasis & highlights:

It's related to text decoration. I propose changing it from ok to advanced.

Line breaking:

Browsers differ in how they handle line breaks for IDEOGRAPHIC SPACE (U+3000).

UAX #14 doesn't make sense for quotation marks in Chinese: https://www.w3.org/2018/05/14-clreq-minutes.html#x02

Counters, lists, etc.:

@counter-style is only supported in Firefox.

Page numbering, running headers, etc.:

We can use some text in the Hungarian Gap Analysis, since it applies to Chinese too:

Although there exist software that supports page numbers and running headers, none of the browsers do. Complex running headers (containing math, tables or other complex content) are not supported anywhere.

OK for me.
