G'dag, Kirsten,
Also, if you have any of the WP Multinational fonts on your machine, there are a lot you can use:
Lower case "n" gives an "a" with accent grave
Upper case "J" gives an "e" with accent ague (sic)
Upper case "P" gives an "e" with accent grave
etc.,
etc.
Just type them, enter, highlight them in the formula bar, and choose the above font. Did I say "just"?
