defined the CIDFont or a face of that name was installed, so
/Ryumin-Light-H findfont in a file that only names it read its strings
byte by byte as a plain font: <467c> came in as "F|" instead of 日.
Ryumin-Light and GothicBBB-Medium, the Japanese CIDFonts a printer

as well. Latin names such as Foo-Bold-H still stay whole.
