From http://en.wikipedia.org/wiki/CJK_Unified_Ideographs:

"However, the source separation rule states that characters encoded
separately in an earlier character set would remain separate in the new
Unicode encoding."

From all the references I've seen this has been applied everywhere and
any failures to roundtrip conversions are considered bugs and I can't
believe that at this point they havn't all been fixed. This is kind of
underscored by the fact that references always point to theoretical
problems rather than actual lists of characters that can't be
converted.

ISTM that since all the mapping tables are public it should be a SMOP
to *prove* roundtrip conversions are safe, or identify the problems.

Have a nice day,
