フォントをロードし、グリフが見つからない場合に出力するのに使用する置換する文字を指定します。U+20AC としてフォントで提供しているユーロサインの出力を様々な表記でデモします。また、フォントで提供されている ffi と表現される合字をさまざまな表記で出力します。フォントで提供されている旧字体の g を出力します。フォントで提供されている旧字体の s を出力します。フォントで提供されていない st の合字を出力します。「glyphcheck=replace」また「glyphcheck=none」オプションを使用してグリフがない場合に置換されます。合字 st が s と t の二つの文字に置換されるよう設定することを「glyphcheck」によって制御します。フォントで提供されていない Ohm グリフを出力します。「glyphcheck」に従って、オメガ文字に置換されます。
