* Changes in Emacs 21.2
-** Emacs now supports ICCCM Extended Segments in X selections.
+** Emacs now supports compound-text Extended Segments in X selections.
Some versions of X, notably XFree86, use Extended Segments to encode
in X selections characters that belong to character sets which are not
-part of the list of standard charsets supported by the ICCCM spec.
-Examples of such non-standard character sets include ISO 8859-14, ISO
+part of the list of approved standard encodings defined by the ICCCM
+spec. Examples of such non-standard encodings include ISO 8859-14, ISO
8859-15, KOI8-R, and BIG5. To paste selections with such characters
into Emacs, use the new coding system compound-text-with-extensions as
the value of selection-coding-system.
