[NTG-context] Indic fonts with MkIV and

Dear all, Recently I read about the use of Harfbuzz-enhanced LuaTeX with LaTeX for writing Arabic. Following that example, I wrote a minimal test text that worked excellently for Kannada script as well: ----- \documentclass{article} \usepackage{fontspec} \setmainfont{Kedage}[RawFeature={mode=harf;script=knda;}] \begin{document} ಇದು ಹೇಗಿದೆ? ನಾನು ಹೀಗೆ ತುಂಬ ಬರೆಯಬೇಕೆಂದು ಯೋಚಿಸುತ್ತಿದ್ದೇನೆ. \end{document} ----- I want to do this in ConTeXt too! Can anyone tell me how to translate “\setmainfont{Kedage}[RawFeature={mode=harf;script=knda;}]” into ConTeXt? This could be the key to using MkIV with Indic scripts. Robert
