Apparently the correct way to set the default font is the following:
(custom-set-faces '(default ((t (:family "Raize" :foundry "raster" :slant normal :weight normal :height 120 :width normal)))))
But it's not portable, that means I cannot copy and paste on a different
init.el on another computer if I don't check the existence of the correct font before.
A solution is to use a conditional. I already modified my emacs configuration to be environment sensitive, but I cannot solve this issue, I mean I did not manage how to correctly extract the statement from the
(custom-set-faces ...) block to use within a
(setq ...), for instance. Or, as alternative, I wonder if I can use an
if() in this case.
