Not sure what kind of localisation are you alluding to here.  I must
confess that I'm relatively ignorant about fonts, glyphs, and shaping,
so I'm probably missing a lot here.  For example, I have no idea what
is a "raw cmap".

AFAIK, this method is only called in Emacs for a combining mark when
we indeed want it displayed as a separate character, with the dotted
circle.  It is normally called for base (non-combining) characters.
