Detecting when Assembler used a Default Font vs. the one specified

Greetings:

I am trying to develop a process that will add page content to pdf documents.

I have DDX written to perform the functions I need.

One area that I need to address is when the font-family in the DDX is not found by LiveCycle, and LiveCycle uses a default font.

I have set the Job Log Level to 'Finest',.

I have run the job with a valid font specified, as well as a bogus font.

For both successful jobs and unsuccessful jobs, I see the same messages:

I see a listing of the default font (Minion Pro).

I see a listing of my input command.

I do not see any indication that a default font was used instead of what was specified.

Is there any way to trap this situation?

Thanks

Mark
