From 7606810b356e9b3fbe1fbf7c7ca6da2e15e32a0e Mon Sep 17 00:00:00 2001
From: Felix Domke <tmbinc@elitedvb.net>
Date: Tue, 3 Apr 2007 20:48:02 +0000
Subject: [PATCH 1/1] encode/decode in fromString/toString so colons and other
 special characters will be saved correctly. This will break existing service
 references with a % in their path, but that shouldn't hurt too much.
