Am I correct in assuming that it is impossible to change font inside MS Word Equation Editor? It seems that normal font changing tools have no effect there. (I’m using Word 2007.) In the Equation Editor settings, I can set the “default font”, but this appears to be the font setting. The repertoire of fonts probably depends on what fonts have been installed in the system, but it seems to consist of a small set of special fonts, all serif fonts.
My specific question is about tensor variables, since the ISO 80000-2 standard specifies that they shall be primarily written using an italic bold letter in a sans-serif font. How could I switch to a serif font just to use some tensor symbols there?
The only workaround I have found so far is to use Plane 1 characters such as MATHEMATICAL SANS-SERIF BOLD ITALIC CAPITAL T (U+1D64F), which can be entered e.g. by typing 1D64F and then Alt X. This seems to work in Word 2007, but it’s rather clumsy. Is there a better way?
