[Tex/LaTex] How to set cambria math as math font for pdflatex
fontspdftex
How can I make pdflatex use cambria for math fonts and uarial for the body font?

As Cambria Math is only available as an OpenType font and necessarily depends on its OpenType Math table, it does not work with pdftex and needs luatex or xetex.
This behaviour is due to a known 'breaking' change in the latest l3kernel release (i.e. one which the team knew altered behaviour but which was felt was the best choice in the long term). As such, unicode-math needs to be updated to conform with the altered l3kernel code.
Temporary fix (use at own risk): Make a copy of unicode-math.sty in your local tree and do a search-and-replace for \l_keys_choice_int, replacing with \l_keys_choice_int \or. That will fix the issue untilunicode-math is fixed officially. (At least it does in my quick tests.)
The fixed unicode-math is now available on CTAN and in TeX Live 2012. As anticipated, this deals with the issue and all is well again.
