Max,
I found the origin of the mysterious "rendering problem" I'd referred to. My computer is missing a font specified in doxygen.css: .fragment { font-family: Fixed, monospace; font-size: 95%; }
The doxygen pdf manual will go, as soon as I have found that friggen font somewhere!
"monospace" is a generic family, which should work everywhere, and should be tried if "Fixed" cannot be found. So, it seems likely that you DO have a font called "Fixed", but it is broken and somehow causes all the characters to not appear.
Max.
