Rendering Emojis with plugins

[scd31]

I'm interested in implementing a plugin which can render emojis. Not all of them, but a few common ones. I wanted to know - is this possible, and are plugins the correct tool for the job?

Thanks!

I don't really remember the details, but it shouldn't be impossible. To make it work, you need a font that has the symbols, or a TextRenderer implementation that does the actual drawing. Then, I think you need to implement Plugin::next_token that recognises the emojis you want to render, and maps them to the correct emoji characters in your font.

I see, thanks. In that case, can I just do all the logic in the custom TextRenderer - no custom plugin required?

It depends on embedded-text, and I don't know if it breaks up :) and such into multiple tokens. If it does, you'll need a plugin to re-merge the emojis before passing to a text renderer (otherwise it'd see a : in one call, and ) in another).

I was actually thinking of emojis like 😄 but I suppose there'd still need to be merging for multi-character emojis, like country flags
