[Tex/LaTex] ± Symbol in text

packagessymbols

I can't get a ± symbol to show up in my .pdf document, whether it be within a table, or in the main body of text. Can anyone offer any assistence ?

I have read everywhere it is \pm and would write as:

50\% \pm 2\%

50\% \pm{2\%}

As well as other variations.

Similar to Christian's answer, but siunitx will deal with the correct typesetting, be it text mode or math mode.

\documentclass{article}

\usepackage[
  separate-uncertainty = true,
  multi-part-units = repeat
]{siunitx}

\begin{document}
Math mode: $\SI{50 \pm 2}{\percent}$

Text mode: \SI{50 \pm 2}{\percent}
\end{document}

Further Enhancement:

Automatically rotate the symbol to be along the path.
Provide a style setting that can be used to customize the symbol

Code:

\documentclass[border=2pt]{standalone}
\usepackage{tikz}

\newcommand{\AxisRotator}[1][rotate=0]{%
    \tikz [x=0.25cm,y=0.60cm,line width=.2ex,-stealth,#1] \draw (0,0) arc (-150:150:1 and 1);%
}

\begin{document}
\begin{tikzpicture}
\draw (0,0)  -- (3,0)  node [midway] {\AxisRotator};
\draw (0,0)  -- (0,-3) node [midway] {\AxisRotator[rotate=-90]};
\draw (0,-3) -- (3,0)  node [midway] {\AxisRotator[rotate=60]};
\end{tikzpicture}
%
\begin{tikzpicture}
\draw (0,0)  -- (3,0)  node [midway] {\AxisRotator[x=0.2cm,y=0.4cm,->,densely dotted]};
\draw (0,0)  -- (0,-3) node [midway] {\AxisRotator[x=0.2cm,y=0.4cm,->,rotate=-90,blue, dashed]};
\draw (0,-3) -- (3,0)  node [midway] {\AxisRotator[x=0.2cm,y=0.4cm,->,rotate=60, red ]};
\end{tikzpicture}
\end{document}

[Tex/LaTex] Insert unicode symbol

You should separate input and output. If you want to print a symbol you at first need a font which contains it. If you want to use normal latex (it will work with xelatex too) you can e.g. use the dingbat font to get an anchor. If you want to use the symbol in the input you must declare it (I'm not sure if the ⚓ copy& paste correctly):

\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}
\DeclareUnicodeCharacter{2693}{\anchor}
\usepackage{dingbat}
\begin{document}
\anchor ⚓ 
\end{document}

With xetex you can use e.g. dejavu sans (if you get the wrong glyph:make sure that you have only version of dejavu sans). Here too you can use commands/other notation if you don't want to use the symbol in the input:

\documentclass[12pt]{article}
\usepackage{fontspec}
\begin{document}
{\fontspec{DejaVu Sans Condensed} ^^^^2693 \char"2693 ⚓}
\end{document}
