Just few days ago I decided to give XeLaTeX a try for its wonderful use of system fonts.

I read a bit on the net about "fundamental lines" to change (I come from LaTeX) which basically boil down to (and correct me if I'm wrong!)


Now this yields very ugly math fonts. I wanted to use "Asana Math" via


but then this happens

! fontspec error: "font-not-found"! The font "Asana-Math" cannot be found.!! <etc.>

I'm using Mac OS X 10.7 with the latest TeX Live distribution (I even ran TeX Live Utility to update anything "updatable" to make sure) and as editor TeX Studio. But I want to underline that this same error happens using the Terminal with

xelatex [-shell-restricted] <filename>.tex

I am "sure" the fonts are installed, at least Tex Live Utility says so. The issues presents even with this MWE


    \sum_0^\infty 1/x^n = \frac{1}{x-1}

Thank you in advance!

P.S.: I am reluctant to call the above MWE. It is not! It'a M inimal N ot W orking E xample!

You need the file extension (this is always the safest way to load a font in any case)
