Are the symbols emojis? Or something else?

It is an emoji, basically I have found the raw unicode character from some website, and copied that to there. So exact rendering depends on the browser's fonts, I guess. I also have these problems with rendering depending on how I see it.

For all emojis (and to some extent, color schemes and names), I haven't put that much thought into it, so if you think about it a bit, please submit it to us. My considerations:

• some of the emoji colors weren't very visible.
• Apparently there are colored and uncolored versions. I haven't fully figured this out yet.
• The box colors are inherited from sphinx_rtd_theme, and the main choice is which sphinx-lesson class inherits from which sphinx_rtd_theme class.

For background: I am trying to add new directives to show function signatures and the emoji is not being rendered. If I try to copy-paste one of the emojis in the current CSS, my Emacs session freezes 😸

I've succeeded by looking up the emoji on emojipedia.org, copying the codepoint, pasting it in CSS, and replacing U+ with \0.

And it seems one needs to stick to old-ish versions of Unicode (at least for me when building locally)

Hm, I guess it's a good idea to not use unicode that's too new, so that it is available on as many devices as possible. I think emojipedia says unicode versions introduced?

[robertodr]

Yes, they list when the emoji was introduced.
