[NTG-context] Easy insertion of Unicode symbols?

I need to insert a few Unicode symbols...(Just the symbols for the solar system planets)... Is this going to be easy - doable inside ConTeXt with a few preparatory mystic runes, or will it require running scripts, moving files around, etc...? The wiki suggests: Use \enableregime[utf] in order to be able to typeset in unicode under ConTeXt. But is it as simple as it looks?
