-------------------------------------------------------------
Also,
the current code uses {{String.getBytes("UTF-8")}}. This will map broken
Unicode characters silently to the "replacement character" -- that is, the
segment store persists a string that does not represent the input.
It might be a good idea to use an API that will actually flags these strings
while getting the UTF-8 representation, see
http://docs.oracle.com/javase/7/docs/api/java/nio/charset/CharsetEncoder.html.
