This tag should be used for questions concerning the mathspec package for XeLaTeX. If your question is about the underlying fontspec package, use the {fontspec} tag instead.
This tag should be used for questions concerning the mathspec package for XeLaTeX. If your question is about the underlying fontspec part, use the fontspec tag instead.
An alternative to mathspec is the usage of unicode-math. This package has different aims, but you may also change the math font in Xe-/LuaLaTeX (mathspec is incompatible with the latter).
