Hi all,
as you know, QuarkXPress 9.5.1 adds the ability to embed fonts that you used in QuarkXPress (OpenType & TrueType only), so that your HTML5-based issues looks like you designed it in QuarkXPress.
Still sometimes you do not want a font to be embedded, maybe because file size matters more than design or because you use a font that is already installed on a device (QuarkXPress by default doesn't embed iOS fonts). Or you do want a custom font embedded though the device has a font installed with the same name but with a different appearance.
For that QuarkXPress has a list of fonts that are not embedded and not referenced in the CSS. You can find the list here:
/Applications/QuarkXPress 9/XTensions/AppStudio/StandardFontList.xml
You can edit that yourself (make a backup before you do).
Remove the specific font in the XML file and it will be embedded. Add the specific font in the XML file and it will not be embedded.
Enjoy!
Matthias
