[Idea] U+FE0E is the key to fix DejaVu Sans and Liberation Sans overriding

[guoyunhe]

I happened to find this table on Wikipedia: https://en.wikipedia.org/wiki/Emoticons_(Unicode_block)#Emoji

This means that monospace fonts like DejaVu Sans and Libreation Sans can avoid overriding colored emoji if they assign their glyph to correct Unicode with U+FE0E instead of U+FE0F.

If we can fix these two font family, then here won't be any other configuration needed.

And here is the list of all supported variants in Unicode 12: https://unicode.org/Public/emoji/12.0/emoji-variation-sequences.txt

So in future, if you specify the correct modifier, it will render emoji version instead of text version, no mater the fontconfig priority.

I am trying to make a web page example for this test.

Found this one from Unicode website: https://unicode.org/Public/emoji/12.0/emoji-test.txt

It has fully qualified and unqualified emojis. Only some unqualified emoji get override by DejaVu Sans, etc. fully qualified emojis are all okay.

This is quite interesting, problem is most of the usage of emoji in the wild seem to use unqualified emoji.
