add pango_fc_font_map_set_default_substitute
added: pango_fc_font_map_set_default_substitute pango_fc_font_map_default_substitute_changed deprecated: pango_ft2_font_map_set_default_substitute pango_ft2_font_map_changed pango_xft_font_map_set_default_substitute pango_xft_font_map_changed Now PangoCairoFcFontMap will call what is passed to pango_fc_font_map_set_default_substitute when it is time. The deprecated functions make calls to the parent (FC) class now. The user-supplied callbacks are executed in the exact same places as before.
