== [css-text] [css-fonts] Variation selectors are underspecified ==
Variation selectors require some extra processing to get them right. 
There are two reasons for this: The 'cmap' format 14 subtable allows 
character mapping to accept variation selectors as input, and 
variation selectors are required for emoji selection but optional for 
other purposes.

This has implications for the `unicode-range` descriptor in 
@font-face, the font matching algorithm, and a possible property being
 discussed at https://github.com/w3c/csswg-drafts/issues/352.

It seems to me that it's valuable for browsers to have 
interoperability regarding variation selectors.

Before making a specific proposal, I'd love to hear from the browser 
vendors about their current (or planned) support of variation
