Re: Is it possible to use UTF8 IRIs in Turtle?

[Jean-Marc Vanel]

As a practical complement to what Andy wrote,
UTF-8 is just like another character encoding.
If you use a well behaved text editor like gvim
 , you can set file encoding to utf-8 by
typing
:set fileencoding=utf-8
and the Turtle or SPARQL you type will be OK.

As an exemple, on one Jena based site I run, searching "Corrençon"
generates under the hood an UTF-8 SPARQL query with text search :
http://semantic-forms.cc:1952/search?q=Corren%C3%A7on

As another exemple, this UTF-8 query on http://dbpedia.org/sparql/ runs
fine:
select distinct * where {
?S ?P 
}

Just write the codepoint you want.

Spaces are never legal in IRIs.

https://www.w3.org/TR/turtle/#grammar-production-IRIREF

then it gets checked as a legal IRI.

\uABCD escapes are allowed.

No.
That puts 3 characters '%'-'2'-'0' into the URI. Not a space.

encode != escape.

If you want to encode, there's code in IRILib.
