Tag characters and in-line graphics (from Tag characters)

Responding to Leo Broukhis:

Not congruently so, yet, in effect, yes, as I have considered including individual OpenType-compatible glyphs in a base character followed by tag characters format. OpenType is a development from TrueType that can achieve more than can TrueType on its own.

There is a little about this in the last two paragraphs of the following post.

There would need to be a few additions to make if work effectively: for example, a value for each of advance width, ascent maximum, descent maximum and fontunits per em.
