If it does resolve IRIs, which I guess most RSS readers do, then yes.
Otherwise no. RDF as such does not require resolution, and therefore
does not require IDNA support.

IDNA support is available in libraries (e.g. libidn or idnkit)
that can easily be integrated into other software (but are a bit
bulky because of the tables needed).
