Rob Vesse updated JENA-785:
---------------------------
Description:
I stumbled on a problem with a SPARQL query, run against Fuseki 1.1.0 and the
latest 1.1.1 snapshot. This is a minimal example demonstrating the problem.
I have the following single triple (based on Lexvo.org) as my dataset:
{noformat}
<http://lexvo.org/id/iso3166/AQ> <http://www.w3.org/2000/01/rdf-schema#label>
"\U00010408\U0001044C\U0001043B\U0001042A\U00010449\U0001043F\U0001043B\U0001042E\U0001043F\U00010432"@en-Dsrt
.
{noformat}
(this is a label in the rather obscure Deseret alphabet - see wikipedia for
details about the script)
Then I ran this query:
{noformat}
SELECT ?label (SUBSTR(?label, 1, 1) as ?l)
WHERE { ?s <http://www.w3.org/2000/01/rdf-schema#label> ?label }
{noformat}
With the text output, I get this:
{noformat}
------------------------------------------------
| label | l |
================================================
| "𐐈𐑌𐐻𐐪𐑉𐐿𐐻𐐮𐐿𐐲"@en-Dsrt | " |
------------------------------------------------
{noformat}
(you may need to install a Deseret font if you can't see the letters above. I
use DeseretBee from here:
http://copper.chem.ucla.edu/~jericks/Fonts/Bee%20Fonts/Sans%20Serif/_DeseretBee2.ttf)
The result is not completely wrong, but there's something fishy about the ?l
binding - it only shows one quote.
With output set to JSON, XML, CSV or TSV, I get this error instead:
{noformat}
Error 500: java.nio.charset.MalformedInputException: Input length = 1
Fuseki - version 1.1.1-SNAPSHOT (Build date: 2014-09-16T13:16:19+0000)
{noformat}
As you can see I'm using the latest Fuseki snapshot from yesterday.
