Add new font - Emoticon Composer

This is a new font that allows one to compose emoticons through overlapping facial elements (uppercase are eyes, lowercase are mouths, numbers are misc elements).

GitHub repo: https://github.com/google/emoticon-composer-font
TTF: https://github.com/google/emoticon-composer-font/blob/master/fonts/emoticon-composer-Regular.ttf
Tech demo: https://google.github.io/emoticon-composer-font/

It'd be great if this could be added to the API.
