For years, I've been using a hobbled together command to get the arc notation as used in the textbooks adopted by high schools in my area. I'm not really all that pleased with the result: it's just barely tolerable. I figured someone in the community here might have a better solution to what I've been getting by with for several years.

%% my poor man's solution to arc notation

    \arc{AC} \\

Check texdoc symbols-a4 for \wide and especially \wideparen. –  Qrrbrbirlbel Feb 4 '13 at 3:13
Did you see the related question frown and mathop/stackrel/overset? You can use \widearc with the kpfonts or fourier packages, but these change your fonts. \wideparen from yhmath or a few other packages, mentioned there, also works. –  Kundor Feb 4 '13 at 3:16

tipa's \texttoptiebar looks useable:

\usepackage{graphicx,tipa}% http://ctan.org/pkg/{graphicx,tipa}
\arc{AC}\ \arc{BAD}\ \arc{ICK}\ \arc{GOOD}
