+** Some characters are displayed by single width glyphs.
+
+In Emacs 23.1, even in a CJK environment, several characters
+(e.g. U+00D7, MULTIPLICATION SIGN) are displayed by a single width
+glyph even if they belong to one of CJK charsets.  This is a known
+problem and will be fixed in the next version.  The workaround at the
+moment is to put something like this in your .emacs.
