Figure out how to support emoji

[llimllib]

ffmpeg doesn't support emoji in any sensible way. They will render it if the emoji are directly in the font, but not otherwise, and the emoji will be colored the same way as the text no matter what emoji it is.

Is there a simple command line tool that will work for rendering a string containing emoji to an image? A quick test of imagemagick showed that it doesn't work.

I think that unless ffmpeg wants to support emoji, this tool pretty much isn't going to be able to do so. Disappointing.
