+** Emacs now supports ICCCM 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
+8859-15, KOI8-R, and BIG5.  The coding system `compound-text'  now
+supports these extensions.  If you don't want this support, set
+`selection-coding-system' to `compound-text-no-extensions'.
