Encoding colour is already a topic in relation to emoji and maybe could
be extended to other characters.

A stateful method, though which might be useful for plain text streams
in some applications, would be to encode as characters some of the
glyphs for indicating colours and the digit characters to go with them
from page 5 and from page 3 of the following publication.

Well, if people were to want to do it, there could be a character
encoded in the Specials section and then use that character as a base
character and follow it with a sequence of tag characters.
