Probably not. Do they have any option to set a flag like "the last
character was a vowel" which can then be tested when the next
character is painted? If so there is a chance of detecting this
efficiently without having to be too clever.
This couldn't be done in a font, but could be done in a rendering
engine like Uniscribe, which keeps track of characters. Font lookups
work entirely in glyph space, so their only connection to characters
is via the font cmap table.

The sight of James Cox from the BBC's World at One,
interviewing Robin Oakley, CNN's man in Europe,
surrounded by a scrum of furiously scribbling print
journalists will stand for some time as the apogee of
media cannibalism.

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?
