SPARQL: format based on Unicode?

Dear RDF Data Access Working Group,

  In http://www.w3.org/mid/43254eca.231195140@smtp.bjoern.hoehrmann.de
I noticed that http://www.w3.org/TR/2005/WD-rdf-sparql-query-20050721/
does not seem to state that the format is based on Unicode; this makes
character classes in the EBNF like [^#xD#xA] ambiguous. Please change
the draft to clearly indicate that the format is based on Unicode and
which characters expressions like [^#xD#xA] refer to.  See also:
<http://www.w3.org/TR/charmod/#sec-RefProcModel>, specifically C070,
C077, C079, and C078.

(Reference to Unicode has been added since, but it seems the current
editor's draft is still unclear about whether e.g. U+0000 may appear
in a query literally or escaped, as there are portability issues for
some of these characters, this needs to be defined more explicitly.)

regards,
