The fallback behavior has to be done at redisplay time. So we are going to invent a new display feature, just to display 2 fancy characters in a specialized mode buffer, and in a way that will support simultaneous display in several different display types? I'd say it's an overkill. Perhaps we should simply compromise and use ASCII art, or no indication at all.
