Idea. Some distributions do compile gawk with locale-sensitive configure
options. So check your LANG and LOCALE settings - mine are:
doing:

seems to work.
I'll give you the results when it is complete.
Excellent, OK.
I have a question regarding VOS. What is the Inference capability of
VOS for RDF ? Is there any documentation regarding that ?
Dynamic generation of triples in the result-sets is described as follows:
Virtuoso SPARQL supports RDF Schema subclasses and subproperties.
The predicates rdfs:subClassOf and rdfs:subPropertyOf are recognized when
they appear in graphs included in a rule set. When such a rule set is
specified as a context for a SPARQL query, the following extra triples are
generated as needed.
For every ?s rdf:type ?class, a triple ?s rdf:type ?superclass is
considered to exist, such that ?superclass is a direct or indirect
superclass of ?class. Direct superclasses are declared with the
rdfs:subClassOf predicate in the rule set graph. Transitivity of
superclasses is automatically taken into account, meaning that if a is a
superclass of b and b a superclass of c, then a is a superclass of c also.
Cyclic superclass relations are not allowed. If such occur in the rule set
data, the behavior is undefined but will not involve nonterminating recursion.
For every ?s ?subpredicate ?o, a triple ?s ?superpredicate ?o is considered
to exist if the rule context declares ?superpredicate to be a
superpredicate of ?predicate. This is done by havingthe triple
?subpredicate rdfs:subPropertyOf ?superpredicate as part of the graphs
making up the rule context. Transitivity is observed, thus if a is a
subpredicate of b and b a subpredicate of c, then a is also a subpredicate
of c.
