I don't think we realised that there was a difference here.  We just
thought that we could shorten the description by converting to IRIs
instead of URIs.

Or we could go back to converting to URIs.

Presumably the IRI spec allows %HH sequences that correspond to
private use characters?  If so, HRRI could add private use characters
to the list to be encoded to produce an IRI.
