Henry,
I think that it would be great to have an OpenACS ISO-8859-1 compliant out-of-the-box!
For now I'm already using ns_startcontent and the browser output is correct, but I don't know how to get input form's data into TCL variables without chars being corrupted. I tried Jonathan's patch #44 but after some initial problem I discovered that my version of AOLserver doesn't support the ns_setformencoding proc and so I stopped the testing.
