We have spent some more time on this and have uploaded a file to the On-line Examples that compares some font options.
Depending on the fonts you have installed you may see something different. One of the fonts demonstrated is Latin Modern Math.
You can download the Latin Modern Math from here. In the download folder, look for the file ‘latinmodern-math.otf’. Double click the file and the font manager should allow you to install.
Here is a graphic we made in DataGraph that demonstrates Latin Modern Math.
Here an example with the equation …
The problem with this character set is that the italic characters are not set up in the standard way, so you don’t see those as an option. This is too bad since for equations that is typically what you want.
Another option is a font called STIX. This is most likely in your system and we have a graphic set up to compare that as well, since it has italic as an option. This is designed for math/technical documentation.
So this is not a complete solution but hopefully gives you some more options until we can figure out a better way.
