How would you
feel about making the phrase something closer to "the basic

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.
Wfm. Tom?
OK (after some thought).
As you surmise, I am not familiar with 'basic Latin' as a term of art
and did wonder if that was intended to exclude digits (since they came
to Europe later, with the Arabs). The NEW text clarifies that.
