Perhaps this is a question of opinion?

Switching on the main checkbox will activate font substitution, otherwise it is off.

If switched on, you can add preferred fonts for substitution and / or all system fonts.

If both options are selected, first the preferred fonts are tried out, then all others.

Perhaps the label of the main switch is misleading and one should write simply
"Font substitution" instead of "Additional fonts with Font substitution".
The longer name of the main switch was given because some people may not know what font substitution is.
