I have written a document containing a formula. I gave it to a friend and when she opened it the user-defined symbols didn't work. What's the matter?

This is a known issue with Math. The user-defined symbols are part of the user settings and are not saved with the formula.

Furthermore the predefined user-defined symbols have localized names, for example %alpha might be %alfa in other languages, so that even these symbols can cause trouble. There is currently no solution to the problem, but it is being worked on.

When you export formulas to MathML the user-defined symbols using the StarMath font are correctly exported, other user-defined symbols are currently not.
