It would be nice to support things like 😊, 😂, ★, 😉, 🎉 in text labels.

I tried installing a font that supports them, and that worked, but they look quite ugly as those fonts don't support color.
Also, the size ballooned, because each font size needs to be added separately.

Therefore, I would propose to add a custom LVGL font parser that replaces each emoji by a corresponding colorful image, preferably scaled to match the size of the font. That way, they look good, and the size will be much smaller than including it in all the fonts.
