In order to make URNs as stable and persistent as possible when
protocols evolve and the environment around them changes, URN
namespaces SHOULD NOT allow characters outside the basic Latin
repertoire [RFC20] unless the nature of the particular URN namespace
makes such characters necessary.

The term "non-ASCII" is defined in RFC 6365 and seems perfectly
appropriate here.
