The manual mentions printing reports in RTF format. I have not been able to do this myself as I don't have access to a fully enabled Ansur (but just a "demo" version).
There is a "Store text as RTF" check-box on the "Edit document properties" form (under the Edit menu). But it's probably best to forget about RTF.
Sadly, it seems that the issues you are facing are not completely
unknown. Also see
here.
I guess what you need is a way to intercept the Ansur-to-pdf routine and inserting your own code. But without access to Ansur source code (or hacking into it), I can't see how that can be done.
Meanwhile, I found this in the file "English (ansur).lng":-
"If User selects Unicode languagues (Ex: Japanese or Chinese) make sure that system locale is changed to respective language and 'Arial Unicode MS' font installed in the PC."
I would have a "play" myself, but to be honest, I don't want to disturb my PC by fiddling about with stuff like that! You know, keyboard settings (mapping), Code Pages and so forth.
Good luck!
