----------------------------------------
[~mkl] thank you for the thoughts there. I've created a Gist to show what I'm
now thinking about doing based on all the comments here. Please have a look and
feel free to comment:

I'm not sure how to parse the *DA* into instructions, find the Font setting one
and grab the first argument. Could you elaborate?
Also, could you elaborate on what the set of Font names that should be
supported, even if they're not found in the *DR*?
Many thanks, again, to everyone!

> The PDF contains sensitive user information, so I cannot post it here
