Description

A RulesetNotFoundException occurs, when loading rules (Rule.rulesFromUrl(..)) from a text file that contains umlauts in comments.

EDIT:

I wasn't aware of that, but yes the file is encoded in latin-1. However, I found it confusing that a 'NoRulesetFoundException' was thrown when the file obviously existed. Apart from the file's location there was no indication of what exactly the problem was.

Anyway, here is the code, a sample rule and the exception I am getting.

Rule.rulesFromURL("file:C:
example.rules");

@prefix ex: <http://www.example.org#>
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
