Slashed Zero Fonts

Hi,

Could you please inform me how to import into Excel 2000 a Font file with
a Slashed Zero number?
e.g. number zero slashed 0 such as in the "Consolas Font file"
I m usng MS Windows XP

The reason is the some of the codes in the cells on my Excel spreadsheet are a mixture of number Zero 0 and the letter O which I find confusing

I have obtained as copy of the Font file with Slashed Zeros from the site below

http://www.wm8c.com/slashed_zero_fonts.htm

Andale Mono Dot
Andale Mono Slashed
Arial Slashed
Crystal
Crisp
Glass Gauge
Ham
Ham Gothic Light
Ham Mincho Light
Monaco
Pro Font Windows
Proggy Clean
Sheldon
T93Y
Tahoma Slashed
Technical Slashed
TI 92 Plus
VAG Round

Hoping you can oblige

Derek
