# Symbol for “care of” (c/o)

Is there a c/o symbol in LaTex for writing an address? I have looked in the Comprehensive latex symbol list but couldn't find one.

I do not think there is such a symbol, doesn people just write c/o? –  daleif Mar 7 '11 at 13:08
DeTeXify doesn't know it :-( –  Martin Scharrer Mar 7 '11 at 13:15
It’s in unicode, however: ℅ –  Debilski Mar 7 '11 at 13:23
@daleif: Actually, when you write 'c/o' in any word processor (MS Word, OpenOffice, Google Docs) it is typeset beautifully, that's why I thought there might be a symbol for that in LaTeX too. –  Dronacharya Mar 7 '11 at 13:59
On page 67 of the symbols list it says: nicefrac (part of the units package) or the newer xfrac package can be used to construct vulgar fractions like \1/2", \1/4", \3/4", and even \c/o" (like @kahens solution I guess) –  meep.meep Mar 7 '11 at 14:02

Probably quick and dirty, see ISO character entities and their LaTeX equivalents on page 3:

${^c\!/\!_o}$ Jim Jones


Edit: Included suggestion from Tobi’s comment having the letters c and o non-italicised:

$\mathrm{^c\!/\!_o}$ Jim Jones

Very dirty ;-) I’d at least add \mathrm to make c and o non-italic … –  Tobi Apr 10 '12 at 13:33
\documentclass[a5paper]{article}
\newcommand{\co}{%
\leavevmode
\begingroup
\setbox 2 = \hbox {\small c}%
\setbox 0 = \hbox {/}%
\dimen 0 = \ht 0  \advance \dimen 0 by -\ht 2
\raise \dimen 0 \box 2
\kern -0.3333\wd0/\kern -0.3333\wd 0
\lower \dp 0 \hbox {\small o}%
\endgroup
}
\begin{document}
\co\space Mr. Bean
\end{document}

The "c" should be level with ascenders and the "o" at the baseline; with textcomp's \textfractionsolidus the slash is slightly better than the normal /; but for symmetry it can be slightly raised up.

\documentclass{article}
\usepackage{textcomp}
\makeatletter
\newcommand{\co}{%
\check@mathfonts
\raisebox{.85ex}{\fontsize{\sf@size}{\z@}\selectfont c}%
\kern-.1em\raisebox{.2ex}{\textfractionsolidus}\kern-.1em
{\fontsize{\sf@size}{\z@}\selectfont o}%
}
\makeatother
\begin{document}
\co\ Mr.~Bean

\end{document}

for whatever it's worth, the image for the unicode symbol (U+2105) shows the letters in italic. –  barbara beeton Jun 7 '13 at 21:27
@barbarabeeton If that's preferred, just change \selectfont into \itshape. –  egreg Jun 7 '13 at 21:31

Another solution. This \co macro is nearly the same that a macro used by LyX to obtain the c/o symbol (\LyXcareof)

\documentclass{article}

\newcommand\co{\mbox{%
\raisebox{.8ex}{c}%
\kern-.175em\raisebox{.2ex}{/}%
\kern-.18em\raisebox{-.2ex}{o}%
}~}

\begin{document}
\co Mr. Bean
\end{document}
