This is what I get if I do C-u C-x = on the character that's displayed in the

  character: ? (3945, #o7551, #xf69, U+00E9)
    charset: latin-iso8859-15
             (Right-Hand Part of Latin Alphabet 9 (ISO/IEC 8859-15): 
 code point: #x69
     syntax: w  which means: word
   category: l:Latin
buffer code: #x8E #xE9
  file code: ESC #x2C #x62 #x69 (encoded by coding system iso-2022-7bit)
    display: by this font (glyph code)
     -Misc-Fixed-Medium-R-Normal--15-140-75-75-C-90-ISO8859-15 (#xE9)

Well, as it works for me, I guess Chris's values are of more interest, but
here they are anyway:
