Ola,
I have VPE 3.5 working with RTF and generating languages like Russian, Bulgarian, Thai, Korean, Simple Chinese, etc. Some languages I have not been able to run succesfully in VPE 3.5 are Hindi (although it can be done using a special font -> Kruti Dev), Complex Chinese and Japanese.
RTF, however, needs some tweaking and trust me when I tell you that it took me a lot of time to make it all work.
I'm not sure if all of this will work in under 4.0 and higher.
Unicode has also been on my list since I started using VPE (over 8 years ago) but it still has not yet materialized.
Regards,
Ron
PS you can check it here:
http://www.akzonobel.com/polymer/msds/index.aspx and select a product, country + language. All documents are generated by Visual Foxpro 8 using VPE 3.5 enterprise edition. We also use the Adobe Generic Postscript printer + Ghostscript and NOT the Idealsoftware PDF engine as this engine will not support the languages that we want. The strange part in this is that VPE will display it correctly...but the created PDF by VPE itself does not. Adobe GPS + Ghostscript solve this issue.
