Equations fonts - Global change

This discussion presume legacy Frame Math. MML in current versions may be completely different.

> The document used Symbol font for all operators including +, -, = etc., ...

Based on this old thread, the default font for math elements is determined (on Windows) by the mathchar.cfg file in the \fminit folder. "Symbol Regular" is the factory default for most math elements (on my 7.0 Windows install).

If Symbol is being used for everything, that's unusual (and also raises the question of TrueType Symbol, Type1 Symbol or OpenType Symbol). If so, do you have any idea how it was accomplished?  But if you are seeing something different than your personal defaults, then the authors of that document had to have applied some formatting to make it happen.

That formatting might take the form of:

• local overrides in each case,
• application of the "EquationVariables" character format (which by default doesn't seem to be applied to anything), or
• hacking of the <DMathAlphaCharFontFamily `font_family_name'> tag in a MIF of the file (which seems to affect only newly authored equations, and not existing ones).

Once you know how it was done, approaches to changing it can be contemplated (more MIF hacking is on the list).
