Hello,
Sorry for top posting.
As far as I aware in the rdf related specs (i.e turtle, rdfxml, and sparql)
there are mentions of two things IRIs and URIRefs. Sparql supports IRIs as it
is newer than both turtle and rdfxml which talk of URIRef. I am not currently
in front of my computer so am linking to an older thread below.
I asked a related question on a public mailing list [1] where I was linked to
the relevant RFCs.
If i recall correctly backtick (which I don't have on my iPhone) is %60 when
encoded as a IRI. So I don't think your claim re percent encoding is true.
I think there is a very small subtle difference between the definition of a
URIRef and an IRI (backtick being one of them). So I would find the definition
of a URIRef and check the uri in question against it.
So, as far as I can tell URI in rdfxml and turtle should be a URIRef and spraql
engines should define URIs as IRI. URIRefs were trying to preempt the iri spec.

Start uncovering the many advantages of virtual appliances
and start using them to simplify application deployment and
accelerate your shift to cloud computing.
