It¼s clear, but it¼s not 100% accurate as far as I can tell:

- C-x = shows 'raw-byte', not 'raw byte'
- It doesn¼t show this for the whole range 0200 to 0377, only for 0240
  to 0377, eg for 0200:

Char: € (4194176, #o17777600, #x3fff80, file #x80) point=1 of 256
(0%) column=0

C-u C-x = gives:

             position: 1 of 256 (0%), column: 0
            character: € (displayed as €) (codepoint 4194176, #o17777600, 
#x3fff80)
    preferred charset: tis620-2533 (TIS620.2533)
code point in charset: 0x80
               syntax: w        which means: word
             category: L:Left-to-right (strong)
             to input: type "C-x 8 RET 3fff80"
          buffer code: #x80
            file code: #x80 (encoded by coding system raw-text-unix)
              display: no font available

Character code properties: customize what to show
