@hijomojo try something like this:
font-family: ‘Jost Regular’, Jost
This could make it work both in View and PDF at the same time.
However, this is really a workaround. I need to implement ability to upload custom fonts to themes directly. This way Manager won’t be relying on operating system for fonts. This will also solve issue where transferring business file between computers - the fonts won’t need to reinstalled as they would be bundled within the custom theme.
