[NTG-context] itemize headstyle SC?

I want an itemized list set in smallcaps. Shouldn't this work? \startitemize[n][headstyle=cap] with a \setupcapitals[sc=yes,title=yes] in the module I'm using? I've run into this problem before with section headings, and not figured it out... Also, what command do I use to invoke a character encoding regime? \usemodule doesn't seem to work... Bruce
