That's an easy macro to add to texvc.js but there are some technical problems.
Mainly, the right(tm) way of doing this in MathML would be using the frown
entity but only the STIX fonts have the necessary stretchy characters AFAIK.
However, both MathJax and Firefox can stretch overparens, so something like
\overset{\mmlToken{mo}{#x23DC;}}{XYZ} would do the trick.

[Bug 30215] Not possible to use \overarc
https://bugzilla.wikimedia.org/show_bug.cgi?id=30215 --- Comment #8 from 石庭豐 seak...@gmail.com --- MathML...? You're talking about the native support from browsers? Well, this bug is talking about math inside Wikimedia/Wikipedia. And in the case when end-user browser cannot accept MathML, Wikimedia should generate an image. So, please limit this bug on the server side. On the other hand, I have just found this article: http://www.tex.ac.uk/ctan/info/symbols/comprehensive/symbols-a4.pdf overarc is inside it, so it looks pretty standard. -- You are receiving this mail because: You are the assignee for the bug.

MathML is part of HTML5, so it should be quite standard. And I think it's a
good idea to the HTML standard and not to invent custom notation or allow the
use of the turing complete programming language \TeX.
And in the case when end-user browser cannot accept MathML, Wikimedia should
generate an image
That's what's being done.
So back to the question: Do you think
\overset{\mmlToken{mo}{#x23DC;}}{XYZ}
would solve the problem?

https://bugzilla.wikimedia.org/show_bug.cgi?id=30215 --- Comment #10 from Peter Krautzberger peter.krautzber...@mathjax.org --- @石庭豐 the new version of the math extension is moving towards MathML, both internally and externally. I.e., TeX input is converted into MathML and rendered into image formats (or just left as is in Firefox). In particular, the mathoid component uses MathJax-node, hence my example of a MathJax-compatible macro. You can try the macro mentioned above on e.g., http://cdn.mathjax.org/mathjax/latest/test/sample-dynamic-2.html to see a sample rendering. It's not ideal but it seems much better than nothing. Note that this is not easy in TeX/LaTeX either, see e.g., http://tex.stackexchange.com/questions/86044/represent-an-arc-over-letters for a solution which is why the old (LaTeX+dvi2png based solution) never added it. IMHO, another plus of physikerwelt's awesome work of moving the extension towards MathML. -- You are receiving this mail because: You are the assignee for the bug.

Thanks! That's the missing part of information I needed to understand.
Converting TeX -- MathML -- PNG well, that's quite an indirect way of
rendering math expressions. But if you are sure it's working at 100%, why not?
:)

I have tried it but nothing is rendered - I could provide a screenshot if you
like. I had also put it inside math.../math tags but still nothing. I had
also tried it in Wikipedia's sandbox but nothing came out (which was expected,
I suppose)

So back to the question: Do you think
\overset{\mmlToken{mo}{#x23DC;}}{XYZ}
would solve the problem?
There are two aspects to this question: 1) rendered result and 2) facility.
For 1: as I cannot see any result, I cannot answer.
For 2: are you saying that
a) Wiki editors have to type your expression instead of \overarc{XYZ} in order
to have the arc symbol? or
b) \orverarc{XYZ} will be translated into your expression internally?
If you're implying a), then the answer is no, it would not solve the problem
because
i) the TeX syntax is overarc (for those who know TeX, of course) but you force
users to use undocumented tweak without telling them what to do exactly;
ii) in the case \overarc is not supported, I would the TeX syntax I provided
(\overset{\frown}{AB}) which is a LOT shorter and cleaner. So the answer is
still No
If you're implying b), of course, that would solve the problem.

石庭豐, thank you very much for providing feedback here.
Of course users are supposed to type \overarc{XYZ} which would then be
internally translated to something else similar to the newcommand LaTeX
command.
See a screenshot of Peters demo page attached.
Screenshots aver very helpful for this kind of bug.

Oh, the dollar sign! :D
OK, visually it's acceptable -- point 1 is OK
Of course users are supposed to type \overarc{XYZ} which would then be
internally translated to something else similar to the newcommand LaTeX
command.
-- point 2 is OK too.
So in all, YES!, the proposal would solve the problem :)
Thanks

Is \overarc supposed to be used in math mode?
I don't understand the question. If math is used, we are in math mode, right?
I want to be able to write math\overarc{AB}/math to show the arc notation.
\overarc should be easy to implement in the MathJax TeX parser (there is no
upstream report so far, though). If the goal is to make the symbol stretch to
cover the base, then stretchy variants will need to be supported by the
MathJax
font (I haven't checked if that's the case).
Please take a look at http://www.codecogs.com/latex/eqneditor.php and put
\overarc{AB} inside the text box to see what's supposed to be rendered.

\overarc is not a standard symbol as far as I can tell, it seems to be part of
\usepackage{arcs}. It's also not part of MathJax.
