[NTG-context] Chinese in utf-8

Hi all. I have ConTeXt set up to output Chinese using usemodule[chinese], all fonts, encodings and maps are installed and the sample file works well. Now I have a whole load of Chinese text in utf-8 encoding. Can ConTeXt process this, or do I have to convert it to another encoding? I tried \enableregime[utf] and \useencoding[uc] but it just produced black blobs instead of Chinese characters. I hope ConTeXt can do it? :-) Thanks, Duncan
