Re: [Rdfapi-php-interest] Still trouble parsing UTF-8: escaped characters returned

Hi Ian,

Thanks for the additional information! I *think* (but haven't =20
actually tried) that a small change in line 1282 of api/sparql/=20
SparqlEngine.php should fix the problem. Could you please try to replace

             $label =3D htmlentities($varvalue->getLabel());

with

             $label =3D htmlspecialchars($varvalue->getLabel());

and report back if it works?

Cheers,
Richard
