Variable name cannot start with ú

[jakubklimek]

When a variable name starts with ú, e.g.

select * where {?ú ?p ?o} LIMIT 100

On https://data.gov.cz/sparql I get

Virtuoso 37000 Error SP030: SPARQL compiler, line 0: Bad character '�' (0xc3) in SPARQL expression at '�'

SPARQL query:

#output-format:text/html
define sql:signal-void-variables 1 select * where {?ú ?p ?o} LIMIT 100

and on https://dbpedia.org/sparql I get

Virtuoso 37000 Error SP030: SPARQL compiler, line 0: Bad character 'Ã' (0xc3) in SPARQL expression at 'Ã'

SPARQL query:
#output-format:text/html
define sql:signal-unconnected-variables 1
define sql:signal-void-variables 1
define input:default-graph-uri <http://dbpedia.org>
select * where {?ú ?p ?o} LIMIT 100

Hi, The way I read the SPARQL spec, this looks like a bug. Have raised a bug internally for tracking.

Cheers,
