You'll have to put the quotes in yourself.
I suggest writing a method `quote` which quotes strings: to begin with
static String quote(String x) {
return "\"" + x + "\"";
}
and then you can write
> "\n FILTER (regex(str(?g),*"+quote(g)+"*)) ." +
of course this breaks as soon as `g` might contain quotes or
backslashes, in which case I suggest
return "\"" + FmtUtils(stringEsc(x, true) + "\"";
which is a method from ARQ that properly quotes strings for SPARQL.
