Had an issue with accented character disappearing when posting data between the Saleslogix and the ASP.NET site. Apparently Saleslogix is still using iso-8859-1 encoding throughout, and ASP.NET does not (by default) decode that correctly. I changed the requestEncoding and responseEncoding to iso-8859-1 under the system.web/globalization element in web.config, hopefully this won’t break anything else.
