If the system needs to display a character that is not present in the selected font, fontconfig attempts to display the character in another, similar font. For example, you might select Bitstream Vera Sans as the font for the Text Editor application. The Bitstream Vera font family does not include Cyrillic characters. If you open a document which contains a Cyrillic character, Text Editor uses a similar font that includes Cyrillic characters to display the character.
Hautatutako letra-tipoan erabilgarri ez dagoen karaktere bat bistaratu behar duenean sistemak, antzeko beste letra-tipo batean bistaratzen saiatzen da fontconfig. Adibidez, Bitstream Vera Sans aukera dezakezu testu-editorea aplikazioaren letra-tipo gisa. Bitstream Vera letra-tipoen familiak ez du karaktere zirilikorik. Karaktere zirilikoak dituen dokumentu bat irekitzen baduzu, karaktere zirilikoak dituen antzeko letra-tipoa erabiltzen du testu-editoreak karaktere horiek bistaratzeko.
