** The utf-8/16 coding systems have been enhanced.
By default, untranslatable utf-8 sequences (mostly representing CJK
characters) are simply composed into single quasi-characters. User
option `utf-translate-cjk' arranges to translate many utf-8 CJK
character sequences into real Emacs characters in a similar way to the
Mule-UCS system. This uses significant space, so is not the default.
By default, untranslatable utf-8 sequences are simply composed into
single quasi-characters. User option `utf-translate-cjk-mode' (it is
turned on by default) arranges to translate many utf-8 CJK character
sequences into real Emacs characters in a similar way to the Mule-UCS
system. As this loads a fairly big data on demand, people who are not
interested in CJK characters may want to customize it to nil.
You can augment/amend the CJK translation via hash tables
`ucs-mule-cjk-to-unicode' and `ucs-unicode-to-mule-cjk'. The utf-8
coding system now also encodes characters from most of Emacs's

variable.
(utf-translate-cjk-unicode-range): New variable.

(utf-lookup-subst-table-for-decode): New function.
(utf-lookup-subst-table-for-encode): New function.
(utf-translate-cjk-mode): Init-value changed to t. Don't load
tables here. Update safe-charsets of utf-* coding systems.
(ccl-mule-utf-untrans): New CCL.
