Fun unicode characters with pandoc

Silly question: I want to use a heart (♥) character in my presentation.

I'm already using xelatex as engine so it doesn't complain for the character itself but it doesn't render it. Just a blank space where the character should be.

Here is the snippet of the offending code:

    (Celery + RabbitMQ) ♥  Django


Notice that I'm using markdown for the input format.

This is how I make the pdf

pandoc -t beamer --latex-engine=xelatex \
in.md -oout.pdf --slide-level=2


I'm new to pandoc and latex in general.

♥ Thanks ♥

Maybe you need this : tex.stackexchange.com/a/9643/9467 – kiss my armpit Aug 22 '12 at 16:20
Great! used $\heartsuit$ instead of ♥ and it worked great. If you put that as an answer i'll accept it. – tutuca Aug 22 '12 at 16:49
Could newunicodechar help? – clemens Aug 22 '12 at 21:38
There was nothing wrong with the edit, so why the bitter remark in the edit reasoning? – percusse Aug 22 '12 at 22:30
Oh, we are kind of hiding in this obscure corner of SE. It's very easy to get rep here so people don't bother with 2 points. Besides, we have the amazing lockstep who is the edit/tag master (probably will visit this question too, check his edit stats :P). Just a reminder Not upvoting is preferred over Downvoting, hence less hassle and moar fun. If you see a question stuck at -1, it means that there is something seriously wrong about that question so we don't downvote more than -1. Other than that it's a pretty relaxed place. – percusse Aug 23 '12 at 6:42

\documentclass{standalone}
\usepackage{arev}
\begin{document}
$\heartsuit$
\end{document}

I just needed to use the latex sintax in the document. Time to learn some more latex. I'm loving pandoc. – tutuca Aug 22 '12 at 22:25

The following works for me:

\documentclass{article}

\usepackage{fontspec}
\setmainfont{XITS}

\begin{document}
♥
\end{document}

If you want a tikzsolution this works

\documentclass{minimal}
\usepackage{tikz}
\newcommand{\heartz}{\begin{tikzpicture}[scale=0.01]
\draw[fill=black,thick,domain=0:2*pi,variable=\t,samples=100] %
plot ({16*sin(\t r)^3} , {13*cos(\t r) - 5*cos(2*\t r) - 2*cos(3*\t r) - cos(4*\t r) });
\end{tikzpicture}}
\begin{document}
\heartz
\end{document}


This code was a result from a small discussion in chat, thanks to percusse.

For the current scale and samples values, there is a glitch at the bottom corner. Increasing either one can get rid of such a glitch. – kiss my armpit Aug 23 '12 at 3:20

Just another fun stuff with PSTricks. Compile the given code with xelatex because the code use JPEG image with which latex-dvips-ps2pdf sequence cannot work.

I'm not sure if I should feel amused, flattered or disturbed :D – tutuca Aug 23 '12 at 1:06
@tutuca: hopefully it is not the last one. :-) – kiss my armpit Aug 23 '12 at 1:08
