I tried '-*-iso8859-1' and it also failed. The problem appears to be in
the Windows implementation of x-list-fonts (w32_list_fonts in
src/w32fns.c). The wildcarding is obviously not working as intended.
(length (x-list-fonts "-*-*-*-*-*-*-*-*-*-*-*-*-iso8859-1"))
= 584
(length (x-list-fonts "-*-iso8859-1"))
= 0
I'll take a look at w32_list_fonts but I am very rusty on Windows
internals.
