Dort steht drin, ob es eine "FixedPitch" (Monospaced) Schrift ist oder nicht:</p> <blockquote> <p>9.8.2 Font Descriptor Flags</p> <p>Table 123 – Font flags</p> <p>Siehe <a class="reference external" href="https://web.archive.org/web/20210128014024/https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf">https://web.archive.org/web/20210128014024/https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf</a></p> </blockquote> <p>Wenn Bit 1 gesetzt ist, ist die Schrift Monospaced.
