[XeTeX] fontspec doesn't like [cm-default]

[Roland Kuhn]

Hi!

Trying to get my Garamond math going I installed the latest XeTeX  
(from svn three days ago), I even got the current latex/base from  
CTAN (put it all into /sw/share/texmf-local, next to my fink teTeX),  
but still there's this annoying error in fontspec:

======================================================================== 
==========

The test.tex file is very basic:

======================================================================== 
==========
\documentclass{article}
\usepackage{xunicode,xltxtra}
\usepackage[cm-default]{fontspec}

\begin{document}

hallo $af\mathrm{af}\rightarrow\mathit{af}$

\end{document}
======================================================================== 
==========

If I copy the fontspec.sty locally into my current directory and  
modify its default to "cm-default" instead of "lm-default" (and leave  
out the option in test.tex) it works, I get a \rightarrow; otherwise  
that glyph is simply missing. So, there are at least two problems here:

- fontspec doesn't cope with options?!?
- lm-default has problems with math symbols (they're in fact all  
missing)

The second one is already kind of explained in the lm README on CTAN,  
which simply states that the OpenType fonts don't have math symbols.  
Can this be worked around by using e.g. Type1?

Thanks,
                     Roland
