Is there a Latex symbol that looks like a sector ⌔ of a circle?

In Unicode, I can find the symbol U+2314 SECTOR:

⌔

Is there something similar in LaTeX?

• You could draw it with pict2e, just a two \lines and one \arc. @Mico It's an unicode character. – Manuel May 19 '16 at 8:40
• Oh no, the wi-fi signal is down! – Paulo Cereda May 20 '16 at 10:17

\usepackage{MnSymbol}


I just searched The Comprehensive LaTeX Symbol List and found it.

• Note you will have to be in math mode: $\downslice$. – user1717828 May 19 '16 at 13:26
• Good but with the same caveat @egreg pointed out to Thomas' answer above: MnSymbol will change a lot of other symbols too. – campa May 19 '16 at 13:32
• Under MnSymbol, there are also \upslice, \leftslice, and \rightslice. – user45727 May 20 '16 at 9:58

This is an implementation using pict2e; the angle is 40 degrees.

\documentclass{article}
\usepackage{pict2e}

\makeatletter
\DeclareRobustCommand{\sector}{\mathord{\mathpalette\make@sector\relax}}
\newcommand{\make@sector}[2]{%
\settoheight{\unitlength}{$#1x$}%
\begin{picture}(1,1.06)
\linethickness{.08\unitlength}
\moveto(0.5,0)
\lineto(0.842,1)
\curveto(.6,1.08)(.4,1.08)(0.158,1)
\closepath
\strokepath
\end{picture}%
}
\makeatother

\begin{document}

$A\sector x$

$A_{x\sector}$

\end{document}


There is a symbol from the fdsymbol package called \sector.

Also, depending on your level of desperation, you might want to look through The Comprehensive LATEX Symbol List.

• Beware that fdsymbol changes almost all symbols. – egreg May 19 '16 at 11:17

The symbol drawn with pgf. The size (\SectorRadius), the angle (\SectorHalfAngle), and the line width (\SectorLineWidth) can be configured:

\documentclass{article}
\usepackage{pgf}

\newcommand*{\SectorHalfAngle}{45}
\newcommand*{\SectorLineWidth}{.4pt}

\newcommand*{\sector}{%
\begin{pgfpicture}
\pgfpathmoveto{\pgforigin}%
\pgfpathclose
\pgfsetlinewidth{\SectorLineWidth}%
\pgfusepath{stroke}%
\end{pgfpicture}%
}
\begin{document}
\begin{tabular}{lc}
Symbol:   & \sector\\
Bolder:   & \renewcommand*{\SectorLineWidth}{1pt}\sector\\
Narrower: & \renewcommand*{\SectorHalfAngle}{30}\sector\\
Wider:    & \renewcommand*{\SectorHalfAngle}{60}\sector\\
\end{tabular}
\end{document}


• Great answer! Is there some way to rotate the symbol 90 clockwise? So it is oriented more like an angle symbol? – Mathemanic Jan 30 '20 at 22:01
• @Mathemanic \rotatebox of package graphics/graphicx, or \sector can be redefined (instead of the more low-level pgfpicture commands, the rotated \sector can also be defined using tikzpicture. – Heiko Oberdiek Feb 10 '20 at 18:37
• I tried using \rotatebox and it rotated successfully, but it ended up drawn strangely below the text line. – Mathemanic Feb 14 '20 at 1:33

You can find a font that has that Unicode symbol (see the list at http://www.fileformat.info/info/unicode/char/2314/fontsupport.htm), install it as a system font, load it using fontspec, and put that symbol directly in your .tex file. Compile with XeLaTeX or LuaLaTeX instead of pdfLaTeX.

\documentclass{article}

\usepackage{fontspec}
\setmainfont{Cambria}

\begin{document}
Here is the symbol: ⌔
