Thanks for coming back to me so promptly

The yellow is the selection and it should not hug the glyphs, but that is a less
horrible symptom than the ghost characters.

This is the output of C-u C-x =

        character: i (105, #o151, #x69)
preferred charset: ascii (ASCII (ISO646 IRV))
       code point: 0x69
           syntax: w 	which means: word
         category: .:Base, a:ASCII, l:Latin, r:Roman
      buffer code: #x69
        file code: #x69 (encoded by coding system undecided-unix)
          display: by this font (glyph code)
    xft:-unknown-DejaVu Sans Mono-normal-normal-normal-*-13-*-*-*-m-0-iso10646-1
(#x4C)

Character code properties: customize what to show
  name: LATIN SMALL LETTER I
  general-category: Ll (Letter, Lowercase)

There are text properties here:
  fontified            t


And no I would not expect Emacs to cope with broken fonts, unfortunately which
ever font a change to I get the same problem.
