How to Produce the Anarchy Symbol

Fancy anarchy with TikZ:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations.pathmorphing}

\tikzset{mydeco/.style={decoration={random steps,segment length=.6,amplitude=.5},decorate,line cap=round}}

\tikzset{anarchy/.pic={
    \draw[ultra thick,mydeco,decorate,red,fill=red](0,0)--(1,.3)--cycle;
    \draw[ultra thick,mydeco,red,fill=red](.2,-.3)--(.5,.7)--cycle;
    \draw[ultra thick,mydeco,red,fill=red](.5,.7)--(.8,-.3)--cycle;
    \draw[red,ultra thick,line cap=round,mydeco](.5,.15) circle(.4);
}}

\begin{document}
Some real \tikz\pic{anarchy};narchy
\end{document}

Also in a more scalable fashion (doesn't scale to \tiny)

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations.pathmorphing,positioning}

\tikzset{mydeco/.style={decoration={random steps,segment length=.08em,amplitude=.05em},decorate,line cap=round}}

\tikzset{anarchy/.pic={
    \draw[line width=.1em,mydeco,decorate,red,fill=red](0em,0em)--(1.2em,.3em)--cycle;
    \draw[line width=.1em,mydeco,red,fill=red](.2em,-.3em)--(.5em,.7em)--cycle;
    \draw[line width=.1em,mydeco,red,fill=red](.5em,.7em)--(.8em,-.3em)--cycle;
    \draw[line width=.1em,red,line cap=round,mydeco](.5em,.2em) circle(.6em);
}}

\newcommand{\anarchy}{\tikz\pic{anarchy};}
\begin{document}

\scriptsize Some real \anarchy{}narchy

\footnotesize Some real \anarchy{}narchy

\small Some real \anarchy{}narchy

\normalsize Some real \anarchy{}narchy

\large Some real \anarchy{}narchy
\end{document}

A variant with tikz with longer horizontal bar:

\documentclass{article}

\usepackage{tikz}

\newcommand*{\AnarchySymbol}[1][50pt]{%
  \tikz[
    x=\dimexpr(#1)\relax,
    y=\dimexpr(#1)\relax,
    radius=\dimexpr(#1)\relax,
    line width=\dimexpr.2\dimexpr(#1)\relax\relax,
  ]
  \draw
    circle []
    (90:1) -- (235:1)
    (90:1) -- (305:1)
    (185:1) -- (-5:1)
  ;%
}

\begin{document}
  \AnarchySymbol
\end{document}

Here are the Unicode code points for anarchic symbols. But the circled A is not at all pleasant. Maybe you have to download some cooler font.... I posted these just so you can see what exists and how to use it.

% arara: lualatex

\documentclass{article}
\usepackage{fontspec}
\usepackage{fontawesome}
\usepackage{booktabs}
\newcommand{\test}[1]{#1 & \setmainfont{#1}\symbol{"24B6} & \setmainfont{#1}\symbol{"2605} & \setmainfont{#1}\symbol{"2691}}

\begin{document}
    \begin{tabular}{lccc}\toprule
        Font& A & Black Star & Black Flag\\\midrule
        \test{Symbola.ttf}\\
        \test{Quivira.otf}\\
        \test{Xits-regular.otf}\\
        \test{Code2000.ttf}\\
        \test{DejaVuSans.ttf}\\
        Font Awesome&&&\faFlag\\\bottomrule
    \end{tabular}
\end{document}

From Mr. Kormylo's comment:

% arara: pdflatex

\documentclass{article}
\usepackage{marvosym}

\begin{document}
\CircledA
\end{document}

And finally, here is the symbol from Wikipedia (I enlarged the horizontal bar for you). As your question was how to produce the anarchy symbol, I will explain that a bit. You download an SVG file from somewhere (like the one provided by Wikipedia) and open it in Inkscape. You will need to install the add-on inkscape2tikz. In Inkscape you choose

Extensions -> Export -> Export to TikZ Path.

The rest should be clear.
