There is another possible way to proceed, namely to use markup bubbles for transmission and to decode them with a local OpenType colour font, where the glyphs of the decoded items are unmapped.

I have successfully tested such a markup bubble technique in monochrome for nine-character markup bubbles, for a different project, using a font made using High-Logic FontCreator 7 and applied using Serif PagePlus X5.
