'guifont' works only in gvim. If has(gui_running) is false, it will
have no effect. Vim running in a terminal will use whatever font the
terminal is using.
This said, even in gvim it is better to use a monospaced font, because
gvim has fixed-size character cells and uses two cells for "wide" CJK

I use consolas font in Vim, but when i open it in Gvim, it appears widened
(because consolas font is monospaced).
So i want to use diffrent font for Gvim and diffrent for Vim.
This is what i placed, but it doesn't work
if has('gui_running')
set guifont=Source\ Code\ Pro\ 10
set guifont=S
