Suzanne Barnhill recently answered this question, but I don't know how to
link to it, so I'll paste her answer here:
The solution that has already been proposed in this thread: an EQ field,
either EQ \o or EQ \x, depending on which gives the result the user prefers.
Here's my usual boilerplate:
There are two ways to create a character with a line over it, both using an
EQ field:
1. Use the EQ \o (overstrike) field to superimpose an overbar (character
0175) over your other character.
2. Use the EQ \x (box) field with the \to switch to put a top border on the
selected text.
The use of the EQ field and its switches is well documented in Word's Help
file.
Whichever method you use, you can save the result as an AutoText entry for
ease of future insertion.

Hope this helps!
