bar and hat only apply to certain letters

Question

I'm a beginner in Mathematica. Like shown in the image below, I'm trying to put hat and bar to some letters (I just want to write vector notation) but only some letters can have them. What's wrong with how I do?

If you could provide online resource that covers these syntax, that would be more appreciable. Thank you.

@rcollyer thanks, I didn't expect there was already a stackoverflow forum for Mathematica. — IsaacS, Feb 01 '12 at 02:01

Use OverHat and OverBar:

OverHat /@ CharacterRange["a", "z"]

Overhat characters

OverBar /@ CharacterRange["a", "z"]

Overbar characters
