Is it possible to use UTF8 IRIs in Turtle?
Is there a way to write UTF8 IRIs with Turtle without all the %-encoded characters? I mean like this <alice smith> or <alizè $mith> or ex:"alice smith"? The only way that I know to write those characters is like this <alice%20smith>, ie. by writing the encoded URI myself. Is there any syntax that I can use to write UTF8 characters instead, and have those characters automatically be parsed as IRIs? Like when I type a string in my browser, I type UTF8 but it's automatically url-encoded to a URL?

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
<https://www.vim.org/download.php> , 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 <http://dbpedia.org/resource/Corren*ç*on-en-Vercors>
}

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.
