20 // nowadays these substitutions are needed for backward compatibility and tight platform integration:
21 // - substitutions from configuration entries (Tools->Options->FontReplacement and/or fontconfig)
22 // - device specific substitutions (e.g. for PS printer builtin fonts)
23 // - substitutions for missing fonts defined by configuration entries (generic and/or platform dependent fallbacks)
24 // - substitutions for missing fonts defined by multi-token fontnames (e.g. fontname="SpecialFont;FallbackA;FallbackB")
25 // - substitutions for incomplete fonts (implicit, generic, EUDC and/or platform dependent fallbacks)
26 // - substitutions for missing symbol fonts by translating code points into other symbol fonts
