Fix encoding of space characters in URI

[charphi]

Current implementation of URI formatting in DataSource and DataSet encodes space characters as + instead of %20.
This comes from backward compatibility in Java URLEncoder.

Is this resolved? I just tested the SNAPSHOT of the v3.2.3 and I still get some + in the path:

I don't have the problem. Try do create a new workspace from scratch. Maybe it is just old URI from previous version.

I downloaded the latest snapshot from this morning and now it works!
Maybe I tested with a too old snapshot...
