*** Visiting a file in unibyte mode.<BR>
Turning off multibyte character support in the buffer after visiting a
file with multibyte code conversion will display the multibyte
sequences already in the buffer, byte by byte.  This is probably not
what you want.
<P>
If you want to edit a file of unibyte characters (Latin-1, for
example), you can do it by specifying `no-conversion' as the coding
system when reading the file.  This coding system also turns off
multibyte characters in that buffer.
<P>
If you turn off multibyte character support entirely, this turns off
character conversion as well.
