My apologies. I replied too quickly. I just wrote this test with
Jena's command line tools. To match the string "+35", I had to use the
"\\+35" in the query:
select ?label where {
values ?label { "+35" "-35" }
filter(regex(str(?label),"\\+35"))
}
---------
| label |
=========
| "+35" |
---------
That's _two_ slashes in the query string, which means that in Java
you'd end up writing
String query = ... + "filter(regex(...,\"\\\\+35\")" + ...;
Sorry for the hasty and inaccurate reply.
