Long time ago I proposed an idea to solve this kind of problems:

http://www.postgresql.org/message-id/20131112.155752.666523035722474275.t-ishii@sraoss.co.jp

The implementation details are not necessarily the best but still I
believe what we need is "round trip encoding conversion safe"
universal encoding for internal use.
