Excel Font question: Can you overscore a character?

[Guest]

I would like to overscore a character within a cell in an Excell spreadsheet.

I am able to add a Equation box with an overscore (insert object, microsoft
equation 3.0, overbar template), but this only seems to work in a floating
text box.

I would like to type in crystollography references -- for instance, inside a
cell
<"one one onebar"> as <111> with a bar over the third one.

Is there any way to type <111> with a bar over the third one in a cell in
Excel?

Thanks,

Joe
