are SPARQL queries unicode?

Björn commented [CMNT] that productions like:
  NCCHAR ::= NCCHAR1 | '-' | [0-9] | #x00B7 | [#x0300-#x036F] | [#x203F-#x2040]
and even
  WS ::= #x20 | #x9 | #xD | #xA
need to specify a codepoint convention for those numbers to mean
anything.

We've since visited this text, but in the interest of clarity, I am
considering changing our current text from:
[[
A SPARQL query string is a Unicode character string (c.f. section 6.1
String concepts of [CHARMOD]) in the language defined by the following
grammar, starting with the Query production.  The EBNF format is the
same as that used in the XML 1.1 specification[XML11]. Please see the
"Notation" section of that specification for specific information about
the notation.
]]

to:
[[
A SPARQL query is a string (c.f. section 6.1 String concepts of
[CHARMOD]) in the language defined by the following grammar, starting
with the Query production.  The EBNF format is the same as that used in
the XML 1.1 specification[XML11]. Numeric references,
e.g. <code>#x27</code> or <code>#xxD7FF</code>, identify charactars by
unicode codepoint. Please see the "Notation" section of that
specification for specific information about the notation.
]]

This says that the grammar is read as unicode codepoints (editorial)
and says that SPARQL Queries are independent of encoding (substantive).
