+ On rare occasions, Emacs encounters @dfn{raw bytes}: single bytes
+whose values are in the range 128 (0200 octal) through 255 (0377
+octal), which Emacs cannot interpret as part of a known encoding of
+some non-ASCII character. Such raw bytes are treated as if they
+belonged to a special character set @code{eight-bit}; Emacs displays
+them as escaped octal codes (this can be customized; @pxref{Display
+Custom}). In this case, @kbd{C-x =} shows @samp{raw byte} instead of
address@hidden In addition, @kbd{C-x =} shows the character codes of
+raw bytes as if they were in the range @code{#x3FFF80..#x3FFFFF},
+which is where Emacs maps them to distinguish them from Unicode
+characters in the range @code{#x0080..#x00FF}.
