I have another question about this change.

      /* Fonts often have characters in other scripts, like symbol, even if they
         don't match script: symbol.  So check if the character is present
         in the current face first.  Only enable for NS for now, but should
         perhaps be general?  */
      Lisp_Object font_object;
      XSETFONT (font_object, face->font);
      if (font_has_char (f, font_object, c)) return face->id;

With it, face->font may vary depending on the preceding
character.  So if you have these lines:
  abc•
  あいう•
the two "•"s will be displayed by different fonts.  Isn't it
better to try the font selected for ASCII as this:

      XSETFONT (font_object, face->ascii_face->font);
