As I wrote in the previous mail, the right way to get the
fontset of the current frame is:
  (face-attribute 'default :fontset)

Then, you can simply modify the default fontset as this:

  (set-fontset-font "fontset-default" 'unicode "Droid Sans Fallback"
  		    nil 'prepend)

The reason for `prepend' is not to loose the original useful
setting for characters not in "Droid Sans Fallback".

Here `t' is the same as "fontset-default".  This facility is
kept just for backward compatibility.
