Benjamin Reed commented on ZOOKEEPER-16:

The following characters cannot be used because they don't display well (or 
render in confusing ways):
 * overlong encodings
 * \u0000 (we use null terminated strings!)
 * \u0001-\u0019,\u00-\u009F.
 * '.' and '..' cannot be path elements. For example, the following would be 
invalid paths '/a/b/./c' and '/a/b/../c'.  (This could result in confusion 
since ZooKeeper does not use relative references.)
 * The following characters are also not valid for use \ud800-\uf8ff, 
\ufff0-\uffff, \uXfffe-\uXffff (where X is 1 to e), \uf0000-\ufffff

Any of these violations should result in an error, decoding should stop, and an 
exception thrown or error returned.
