Yes.

The restrictions for anchor names come from the HTML specification,
not the url syntax.  And the names used in HTML often have to correspond
with css selectors and identifiers in other contexts, which is why it
limits names to US-ASCII.  

I do agree that the limitation of HTML names to US-ASCII is probably
too strict in the long run, but the only sensible answer will probably
be to use utf-8 encodings, and there are lots of reasons why the
world is just not in a position to be able to do that yet.
And I suspect that allowing Latin-1 or other ISO-8859-* sets in 
HTML names would end up being a huge mistake in the long run.

To answer your question slightly differently:  The scope of things
that urls are intended to cover is much larger than just HTTP and
HTML, so the generic url specification imposes far fewer restrictions 
than what we might find for a particular scheme or resource.
