[NTG-context] Russian sentence in Czech text in Mark II in ConTeXt Suite installation on Linux in UTF8

Hallo. I have to typeset one Russian sentence (cyrillic) in a Czech document in ConTeXt Mark II (texexec) in ConTeXt Suite (minimal installation) on Linux. I use UTF8 encoding. Is there any simple way to do it? I'm willing to accept any font to avoid font difficulties. Can you help me please? Many thanks. Best wishes, Michal
