the messy part is that
- a macron has no stretch
- an overbar has stretch
so, while there is a lot math stuf (now) in unicode, the macron is used
for an overbar which is rather strange; do they also 'misuse' the
underscore for underbar etc?
now an implementation needs to adapt to math or text (or just gamble
since it may be that i want a non stretchable macron over x+y+z); my
guess is that as a result, many implementations are more complex than needed
(btw, in pure text, it's still not clear if the macro glyph sould be
chosen or a stretchable hrule)
(i think that one problem of unicode/xml/mathml is that it is used in
typesetting systems but not in all aspects is designed (or used) to
facilitate high end results; therefore a 24/32 bit tex still needs to
provide much detailed control)
