Yes, thanks, that worked!

Is it possible to also apply this to characters such as », ·, ¢? They seem to have a similar problem, and they're all within the 128..255 code point range.

I've tried:

(set-fontset-font "fontset-default" '(128 . 255) "-misc-fixed-medium-r-normal--13-120-75-75-c-70-iso10646-1")

..but that seems to have no effect.

I've discovered M-x describe-char, and for ¢ (the cent symbol) it shows:

             position: 1669 of 2588 (64%), column: 0
            character: ¢ (displayed as ¢) (codepoint 162, #o242, #xa2)
    preferred charset: unicode (Unicode (ISO10646))
code point in charset: 0xA2
               script: latin
               syntax: _ 	which means: symbol
             category: .:Base, j:Japanese, l:Latin
             to input: type "C-x 8 RET HEX-CODEPOINT" or "C-x 8 RET NAME"
          buffer code: #xC2 #xA2
            file code: #xC2 #xA2 (encoded by coding system utf-8-unix)
              display: by this font (glyph code)
    xft:-Misc-Fixed-normal-normal-normal-ja-13-*-*-*-c-120-iso10646-1 (#x63)

Even though "preferred charset" is "unicode", it seems to prefer using a Japanese font for this symbol oddly enough.
