Appending field values to one rti field in a different document

I have got say 2 docs each with body fields and in mime format. I then need to create a new document that has ONE richtext field made up of the doc1’s body & doc2’s body.

The moment I try to get body1 to do the appendRTItem call to the new richtext field I lose the formatting.

I have tried using the convert mime call etc but without much success.

Any ideas on this one. Is there a way of using the notes C/C++ API - I could try it out as well as I got some understanding of how to use notes API.

thx
