Hi, The ExternalFonts class does some magic. What I mean is the magic around substitutes and windowsToPsName.
I have my own FontProvider and I want to do that things in my class (or not). So why not create a delegating SubstitudeFontProvider which does this substitude logic? And delegates the real get font methods to another provider (in default case the current default FileSystemFontProvider). I offer myself to implement this. Kind regards, Cornelis Hoeflake
