> SPARQL: EBV of "a"@en should be true but is false

> The first has a result, the second doesn’t. Tested on sparql.org.
> According to what I think is [the relevant bit of the
> spec|http://www.w3.org/TR/sparql11-query/#ebv], both should be true because
> they are plain literals and have non-zero length:
> bq. If the argument is a plain literal or a typed literal with a datatype of
> xsd:string, the EBV is false if the operand value has zero length; otherwise
> the EBV is true.
