etc/NEWSより:
** The utf-8 coding system has been enhanced. Untranslatable utf-8
sequences (mostly representing CJK characters) are 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. The utf-8 coding
system will now encode characters from most of Emacs's one-dimensional
internal charsets, specifically the ISO-8859 ones.
