> Makes me wonder, though, is there enough space in unicode to just encode every possibly 16x16 bitmap? Space is not an issue here. You can do with very few characters, just make them combine with each other, like ˩˥ is encoded as ˩+˥, flags are encoded as combinations of two letters, etc. So, you can just have 256 characters for each bitmap dot and make them combine with each other. Or have 16 characters and make them combine (maybe using zero-width joiner). I think the biggest problem is actually getting this thing into Unicode. Emoji got codified because some Japanese phone encodings included them. But it would be harder to justify arbitrary bitmaps.
