Either I have not made myself clear or my understanding of the rendering
process is even less than I thought. Perhaps I should have said "glyph"
rather than "character". But the real point is that I am suggesting some
kind of flag which could be preserved from outputting on glyph to
outputting the next, on the lines of "the last glyph I output was a
vowel" or "... a consonant" - with "vowel" or "consonant" defined simply
as one of a particular list of glyphs or combinations. Is that
possible, or is the rendering engine unable to preserve any kind of
state from glyph to glyph?
