[XeTeX] Roman Numerals as stylistic alternatives

[Tobias Schoel]

Hi,

you totally misunderstood my intentions. I don't want to use neither Ⅰ, 
Ⅱ, Ⅲ, Ⅳ, … (u2160-u217f) nor I, II, III, IV, … (letters). I want to use 
something along "Henri {\fontchangingcommand 4} was a foobar king."

Is \fontspec capable of doing this?

bye

Toscho
