The best example of Unicode 13.0 (2020) Smile/EMOJI

The Unicode consortium has released version 13 of the Unicode standard. The release includes 55 new characters and emoticons 5875 characters are not emoticons.

This follows the announcement last month of the final list of 117 new emoticons for 2020 and paves the way for adding support for new emoticons on the main platform during the year.
I’d love to add in the Browser these emoticons. In windows 10 with this problem because there are only simple Microsoft emoji. What is there in Linux ?

mmm there are few icons in windows but they are so necessary and convenient.
