I would have thought it's obvious that we mean lexical order
by unicode code-point. I thought there must be
some anchor in [CHARMOD] for that, but while I was looking, 
I found...


C066  [S]  [I]  Software that allows users to sort or search text SHOULD
allow the user to select alternative rules for collation units and
ordering.

There was some discussion in IRC of whether the SPARQL QL spec has
user-selectable collation units, but I didn't understand the conculsion,
if there was one.

So, firstly, question of fact: where's the relevant text in rq23?
Does it specify user-selectable collation units?
 If so, let's have a test. Is there one? Has anybody passed it?

 If not, does it say why not? [CHARMOD] C066 says it should,
 so we owe and explanation as to why not.
