FontAwesome and Xelatex

[kaba2]

The following does not work in XeLaTeX on the current MiKTeX version:

\documentclass[border=10pt, multi]{standalone}
\usepackage{fontawesome}
\standaloneenv{sym}
\begin{document}
\begin{sym}\faUserPlus\end{sym}
\end{document}

XeLaTex stops on the following error:

xdvipdfmx:warning: Invalid CMap
xdvipdfmx:fatal: pdf_ref_obj(): passed invalid object.
Output file removed.

The symbol itself is not relevant; the example does not work on most symbols. This has recently been discussed here by someone else. There a workaround is given to insert the following before \usepackage{fontawesome}:

\usepackage{fontspec}
\defaultfontfeatures{Extension = .otf}

I don't know if this is a bug, but it is certainly confusing, because there is no hint on how to fix the problem.

Hi @kaba2, I've encountered the same issue (I don't think it's an xdvipdfmx matter as XeLaTeX can't even produce XDV files). This is indeed a bug of this package and I submitted a pull request that fixes this. A small explanation behind the error is also in the PR.

If you are still interested in this problem, you can try my search-xelatex branch.
