The OP uses MS-Windows.
This bug report is complicated by 2 factors:
. specifying a font for a face actually affects directly only the
ASCII characters; non-ASCII will not necessarily use that font if
the default fontset says otherwise, or if Emacs thinks that this
font cannot support those non-ASCII characters;
. specifying :family in a face doesn't work very well on Windows,
because the Windows API for enumerating fonts that belong to a
family only finds 4 font variants: regular, bold, italic, and
bold-italic; it doesn't find any other variants -- this could
cause some font families to be rejected
