we are having significant rendering issues that seem to come down to the default font not working as a good substitute. i would love to have a lookup table for specific fonts that would then substitute a different installed font.
for example, libreoffice has created opensource metric equivalent fonts for many proprietary fonts. it would be great to be able to configure groupdocs substitute a specific opensource font for a specific closed source font.
Times New Roman = LIberation Serif
Calibri = Carlito
Cambria = Caladea
