+ * This class provides methods to deal with encoding and decoding url (percent encoded) strings.
+ *
+ * It was not possible to use PHP's built-in methods for this, because some clients don't like
+ * encoding of certain characters.
+ *
+ * Specifically, it was found that GVFS (gnome's webdav client) does not like encoding of ( and
+ * ). Since these are reserved, but don't have a reserved meaning in url, these characters are
+ * kept as-is.
