Ok, I understand. Do you know if it's using AddFontMemResourceEx()? 
(should be visible with +font log).

Regarding documents, if fonts they are using are freely to distribute, 
it would be enough if you extracted font blob from one of them.

If it's not possible, do you know which tables are still there in 
embedded font?
