For euro sign, currently these fallback fonts (try M-x
describe-fontset RET RET) are tried in this order by
default.

    -*-*-*-*-*-*-*-*-*-*-*-*-gb2312.1980*
    -*-*-*-*-*-*-*-*-*-*-*-*-gbk-0
    -*-*-*-*-*-*-*-*-*-*-*-*-gb18030*
    -*-*-*-*-*-*-*-*-*-*-*-*-jisx0208*
    -*-*-*-*-*-*-*-*-*-*-*-*-ksc5601.1987*
    -*-*-*-*-*-*-*-*-*-*-*-*-cns11643.1992-1
    -*-*-*-*-*-*-*-*-*-*-*-*-cns11643.1992-2
    -*-*-*-*-*-*-*-*-*-*-*-*-cns11643.1992-3
    -*-*-*-*-*-*-*-*-*-*-*-*-cns11643.1992-4
    -*-*-*-*-*-*-*-*-*-*-*-*-cns11643.1992-5
    -*-*-*-*-*-*-*-*-*-*-*-*-cns11643.1992-6
    -*-*-*-*-*-*-*-*-*-*-*-*-cns11643.1992-7
    -*-*-*-*-*-*-*-*-*-*-*-*-big5*
    -*-*-*-*-*-*-*-*-*-*-*-*-jisx0213.2000-1
    -*-*-*-*-*-*-*-*-*-*-*-*-jisx0213.2004-1
    -*-*-*-*-*-*-*-*-*-*-*-*-jisx0212*
    -*-*-*-*-*-*-*-*-*-*-*-*-iso10646-1
    -gnu-unifont-*-*-*-*-*-*-*-*-*-*-iso10646-1
    -mutt-clearlyu-*-*-*-*-*-*-*-*-*-*-iso10646-1
    -misc-1col-*-*-*-*-*-*-*-*-*-*-iso10646-1

And, in Japanese language environment, the priority for
jisx0213.2001 gets higher than Big5.  But, if a character
has `charset' property, a font corresponding to that charset
register gets the highest priority.

I'll add that in fontset.el

It may be possible to avoid using a font that has empty
glyph for non-spacing characters.  I'll put that in my todo
list.
