wxWidgets/include/wx/fontenum.h
Vadim Zeitlin 36f210c81e 1. added encoding param to wxFontEncoding::EnumFamilies() which allows to get
the list of families supporting the given encoding
2. added encoding decoding logic to src/gtk/font.cpp so that now choosing an
   encoding different from default in GTK+ font selector dialog actually works
