Luc, I think the text is needed and correct. When I raised it yesterday, I was mildly concerned about possible confusion between: "|charset| --- this parameter is required when transferring non-ASCII data. If present, the value of |charset| is always|UTF-8|." and: "The encoding is always UTF-8" Technically, of course, there is no problem, as ASCII codepoints are unchanged by UTF-8 encoding. ... The only change I can suggest, bit I don't think it's really needed, is: "The encoding is always UTF-8 (where ASCII codepoints are also valid UTF-8)". or maybe just: "The encoding is always UTF-8 or ASCII". #g -- On 06/07/2012 08:15, Luc Moreau wrote: > > > Hi Graham and Sandro, > > As indicated yesterday, both turtle > http://www.w3.org/TR/turtle/#sec-mediaReg and > sparql > http://www.w3.org/TR/rdf-sparql-query/#mediaType > use the same sentence I adopted for PROV-N: > > > Encoding considerations: > The syntax of Turtle is expressed over code points in Unicode > [UNICODE <http://www.w3.org/TR/turtle/#bib-UNICODE>].
