Looking for some information or guidance on the Font Substitution Configuration file that is optionally browsable in the Optimize node.
The documentation simply states the following:
Font Substitution Configuration File: Defines the pdfToolbox configuration file that will be used when embedding fonts. This configuration file controls font substitution behavior in Optimize. Fonts are embedded as subsets. Fonts are not embedded if they have a flag indicating that embedding is not allowed.
What does this function allow me to do, and is there a sample availabe that I can see how it is configured?
Is it necessary to use the "Embed Fonts if Needed" in the optimize setup?
