?subject text:query (rdfs:label "...")
if the value "..." contains any special character like : or / Lucene throws an
exception. Is there any SPARQL function that I can use to automatically escape
that string, something like
?subject text:query (rdfs:label ESCAPE ("..."))
or do I have to escape it myself? In this case, do I have to escape anything
else besides the : and / symbols?
