A charset like greek, latin,… I suppose.

But U+0102 gives the right character ‚€‘ (EURO).

No, it's utf-8 both times.

I suppose from fontconfig, because they are anti-aliased, how do I
determine this?

Yes.

  (set-fontset-font "fontset-vera11"
    'mule-unicode-0100-24ff '("dejavu sans mono" . "iso10646-1"))

shows the correct Euro-sign ‚€‘ but

  (set-fontset-font "fontset-vera11"
    'mule-unicode-0100-24ff '("bitstream vera sans mono" . "iso10646-1"))

shows a ‚¤‘. Other applications work fine with Vera, so the problem
depends on emacs /and/ bitstream vera sans mono.
