Wener,

I don't know if there is OpenType/CFF equivalents of the Blue Sky
Research/Y&Y based Computer Modern fonts, but if they exist, you'll want to
check them out.  They use the div operator (which isn't really that exotic,
it's in the Type 1 spec and is used in the Type 1 flavor of the above
fonts).

I suppose I could download the OpenType FDK from Adone and convert the
BSR/Y&Y fonts that can be downloaded from the AMS.

Tom
