This is it

This is it (in both Emacses)
752 (#o1360, #x2f0, ?˰)

 Ok, this is the Guix Emacs
             position: 283 of 860 (33%), column: 30
            character: s (displayed as s) (codepoint 115, #o163, #x73)
    preferred charset: ascii (ASCII (ISO646 IRV))
code point in charset: 0x73
               script: latin
               syntax: w     which means: word
             category: .:Base, L:Left-to-right (strong), a:ASCII, l:Latin,
r:Roman
             to input: type "C-x 8 RET HEX-CODEPOINT" or "C-x 8 RET NAME"
          buffer code: #x73
            file code: #x73 (encoded by coding system utf-8-unix)
              display: by this font (glyph code)
    xft:-PfEd-DejaVu Sans-normal-normal-normal-*-13-*-*-*-*-0-iso10646-1
(#x56)

Character code properties: customize what to show
  name: LATIN SMALL LETTER S
  general-category: Ll (Letter, Lowercase)
  decomposition: (115) ('s')

There are text properties here:
  face                 variable-pitch
  help-echo            [Show]



And this is the Fedora Emacs

             position: 235 of 883 (27%), column: 35
            character: s (displayed as s) (codepoint 115, #o163, #x73)
    preferred charset: ascii (ASCII (ISO646 IRV))
code point in charset: 0x73
               script: latin
               syntax: w     which means: word
             category: .:Base, L:Left-to-right (strong), a:ASCII, l:Latin,
r:Roman
             to input: type "C-x 8 RET HEX-CODEPOINT" or "C-x 8 RET NAME"
          buffer code: #x73
            file code: #x73 (encoded by coding system utf-8-unix)
              display: by this font (glyph code)
    xft:-PfEd-DejaVu Sans-normal-normal-normal-*-19-*-*-*-*-0-iso10646-1
(#x56)

Character code properties: customize what to show
  name: LATIN SMALL LETTER S
  general-category: Ll (Letter, Lowercase)
  decomposition: (115) ('s')

There are text properties here:
  face                 variable-pitch
  help-echo            [Show]


But anyway, I made a little screenshot with Shutter just to make the
difference between the minibuffers more evident
