Corrupt pdf if footprint contains parentheses

works_only_on_older.kicad_pcb

Description

If the description in a footprint contains parentheses, the pdf that is plotted seems to be somewhat corrupt. The menu that shows info about the footprint is not being shown when the footprint is clicked. Also, PyMuPDF is not able to work with the pdf but throws an error.

I don't know if parentheses also causes problem in other fields then the footprint description...
