(cl-pushnew '(w32 (font . "Consolas-16"))
            window-system-default-frame-alist)

or 

(add-to-list 'default-frame-alist '(font . "Consolas-16"))

To set the default font as Consolas-16 in w32 system.

To specify font for fontset, cjk etc., I use the code below and actually
make it a function and call it in after-make-frame-functions (new frame
in daemon mode) or call it after-init-hook (intended for runemacs with
`if (not (daemonp))`).

(dolist (charset '(kana han cjk-misc bopomofo chinese-gbk gb18030))
  (set-fontset-font nil charset
                    (font-spec :family "Microsoft Yahei")
                    nil 'prepend))

However with the setting of window-system-default-frame-alist or
default-frame-alist above, it takes no effect until I make a new frame
(after-make-frame-functions). Emacs takes font for the fontsets above
according to Windows font fallbacks, e.g., MS Gothic.


Finally, I find that if I put `(set-frame-font "Consolas-16" nil t)` in
my dot.emacs, the font setting for above fontsets works in runemacs case
without additional frame make action.
