Controls the use of the Isogen font information (FIF) file. If required, it can be used to turn off the use of fonts in the Isogen output files. By default, there is always a path to the supplementary fonts file. If one does not exist, for example, you delete it, it is recreated automatically. However, if you select Enabled, this setting is persisted.
When importing a style, Enabled is turned off before import starts, and only resets if there was previously a FONT-INFORMATION-FILE (or IDF -152 record) reference in the imported style.
