The symbol I'm after is ⟳ (also nice to have ⟲). That's U+27F3 (and U+27F2). Detexify can't find it (or my drawing skills are woeful); is it already in a font package, or do I have to load it from STIX?

A more general question would be: if I already know the unicode symbol, how do I find out which package supports it?

  • Note: I feel sure we've had this one before, but I couldn't find it. If anyone can find it, I'll happily join the "duplicate" throng. Commented Jun 22, 2011 at 8:31
  • It wouldn't be too hard to draw it in TikZ, but I guess that's not the point...

    Have a look at “How to look up a math symbol?” for ideas how you can easily find a particular symbol. :)

I found them in MnSymbol as \lcirclearrowright and \rcirclearrowleft. Either use the similar symbols in mathabx, rotating and reflecting them, or go with these and my answer on how to import a symbol from a different font

Using the latter way has the advantage that the symbols change size in subscripts and superscripts. Of course it's easy to do this also with the mathabx symbols (via \mathchoice).


Can also be rotated with less or more than 180 degrees

$\circlearrowleft \circlearrowright $

$\Circlearrowleft \Circlearrowright $

$\CircleArrowleft \CircleArrowright $

enter image description here

  • For the symbols I want, I guess I'd want to rotate them by 90 degrees. (I notice that mathabx defines \righttoleftarrow which is almost what I want except that it isn't circular.) Commented Jun 22, 2011 at 9:02

    \circlearrowleft is already contained in amsmath, no need to load mathabx.

    @Carambir: It is in amssymb, not amsmath and it is not the same, the lines are less thick

For future reference: finding special symbols, in particular if you know their names, is fairly straightforward using the symbols documentation (texdoc symbols in a terminal).

Searching the document for “circlearrow” (or “circle arrow”) yielded the MnSymbol package and the macro names. Some viewers (e.g. Skim on OS X) even support searching for Unicode symbols, and searching for “⟳” also worked.

  • I've gotten so used to detexify that I figure that if it doesn't even come close then it isn't in symbols so I('m ashamed to say I) didn't look there! But I wouldn't have known what to search for since I didn't know about the unicode search facility (have to check that in Linux PDF readers) and I didn't know their names.
