I am using XeLaTeX with the packages fontspec,xunicode,xlxtra
(which I believe is pretty standard) to process my documents into a PDF file with the TeX Gyre Pagella font.
I have been doing so successfully for quite some time, but when using the standard LaTeX symbol \hbar
, upon processing an error is thrown
LaTeX Warning: Command \hbar invalid in math mode on input line 86
and the symbol appears instead as a regular "h" which partially overlaps with the previous character.
Here is a minimal code example:
\documentclass{article}
\usepackage{fontspec,xunicode,xltxtra}
\defaultfontfeatures{Mapping=tex-text}
\setmainfont{TeX Gyre Pagella}
\begin{document}
hbar by itself: $\hbar$\\
hbar with a preceeding character: $o\hbar$
\end{document}

It seems to be a bug with
xunicode
.Mixing Computer Modern Math with Pagella (Palatino) is not a good choice (but this is not related to the problem).
