Unfortunately there is no easy way. \mathcal is hardwired to the cmsy10 font internally in LyX. Furthermore, the symbols are addressed using the internal font encoding and not unicode. This is really ugly, but it works for the characters supported by standard LaTeX, and so far nobody volunteered to refactor this part of the code and make it more robust. For those who are interested: There is a big comment in GuiPainter::text(). You can also search for CMSY_FAMILY in the sources. Georg
