Thank you for your message. I did the syntax modifications and included the parameters sugested by you, but the problem continue.
Any other suggestion?
Thanks again!
ns_section ns/encodings ns_param .adp "utf-8" ns_param .html "utf-8"
maybe that's the reason (I don't use that section myself and get my adp files in utf-8 with no problem).
If it still fails after that, check again the encoding of your adp file just in case.
