+** Limited support for character `unification' has been added.
+Emacs now knows how to translate between different representations of
+the same characters in various Emacs charsets according to standard
+Unicode mappings. This applies mainly to characters in the ISO 8859
+sets plus some other 8-bit sets, but can be extended. For instance,
+translation works amongst the Emacs ...-iso8859-... charsets and the

You can force a more complete unification with the user option
unify-8859-on-decoding-mode. That maps all the Latin-N character sets
into Unicode characters (from the latin-iso8859-1 and

** There is support for decoding Greek and Cyrillic characters into
