Hi Martin,
you are right, objects 11 and 13 are pointing to the same
/FontDescriptor but to different /Widths and /Encoding arrays.  The
reason is that the Cyclop fonts contain both, normal and small caps
within the same /FontFile.

Apparently pdfsizeopt.py doesn't check properly whether these objects
refer to the same /FontFile.  Sorry for the noise.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
