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
+Custom}). In this case, @kbd{C-x =} shows @samp{raw-byte} instead of
@samp{file}. 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
