Hi!

I'm new to the list and to the whole Linked Data thing altoghether, but 
will have to work on it for some time so I'll be exploring the DBpedia 
SPARQL end-point for a project we are working on.

The thing is, it is based on Portuguese resources, and I was wondering 
first of all what is the general feeling on working with DBpedia on 
other-than-english resources.

For example, (and this is my concrete question), is there a way to 
correctly order results so accented characters are also correctly ordered?

If I try this example query on http://dbpedia.org/sparql :

SELECT ?label
WHERE {
[] skos:subject <http://dbpedia.org/resource/Category:Portuguese_writers> ;
    rdfs:label ?label .

FILTER ( langMatches(lang(?label), "PT") )
}
ORDER BY ?label

I get this results 
http://dbpedia.org/sparql?default-graph-uri=http://dbpedia.org&should-sponge=&query=SELECT+%3Flabel%0D%0AWHERE+{%0D%0A[]+skos:subject+%3Chttp://dbpedia.org/resource/Category:Portuguese_writers%3E+;%0D%0A+++rdfs:label+%3Flabel+.%0D%0A%0D%0AFILTER+(+langMatches(lang(%3Flabel),+%22PT%22)+)%0D%0A}%0D%0AORDER+BY+%3Flabel&format=text/html&debug=on&timeout=

Notice that at the end

...
Urbano Tavares Rodrigues
Vasco Graça Moura
Vitorino Nemésio
Álvaro Cunhal

"Álvaro" gets incorrectly ordered at the end.

Is this dependent on the underlying store (much like SQL collations)? Is 
there something that can be done on my side to get this query ordered 
like it should be for Portuguese / UTF8 (some notation in SPARQL or 
specific to DBpedia / Virtuoso )?

Thanks and keep up the good work!! This is a truly impresive project!

Regards,

Alex
