I have a situation where I need to be able to modify the font of individual
characters depending on another cell. Specifically, if a cell value is "a",
I need another cell to say "fP", where f is the greek letter phi. If the
first cell vaule is "b", I need to display "P/W" where W is the greek letter
omega. The rest of the cell is regular fonts (arial). How can I do this? I
looked into conditional formatting and it does not appear to be the correct
tool.

Thanks.
