I have a document that includes some mathematical characters. Here's an example:

~(A ∨ B)

The problem is, some of these get blanked out sometimes in calibri font. If I cut and paste (or change fonts) they're then visible again. I've noticed this before with other special characters. The issue seemed to fix itself then.
