CombineCharacters is a newer article that hasn't made it over the awareness
threshold of a lot of those who answer questions. <g>
I was assuming from your post that probably the new Office 2007 fonts do
include these characters, but of course even a lot of Word 2007 users are
still stubbornly using TNR and Arial (with some justification). I would
imagine that the alignment of the diacritics must be improved in Calibri and
Cambria, but it is definitely not acceptable in TNR.

It's in both those fonts, in Vista/2007, between the macron U0304 and
the breve U0306. (OP didn't specify his version.)
The way Word2007 and Vista interact with OpenType has been improved
since previous versions, and I get properly centered overbars using
that character (over both capitals and lowercase). Word treats the
letter as a unit character for editing -- italics, deleting, etc.
As you can see in the two examples you commented on today, when The
Others address this question, they send people to your Overbar article
rather than your Combine Characters article.
