Because these characters are from the Private Use Area, Emacs cannot 
assume that just because a font has glyphs at those code points that 
they are the right glyphs. You will need to explicitly tell Emacs that 
you want to use Code2000 to represent the PUA range:

(set-fontset-font t '(#xe000 . #xf8ff) (font-spec :family "Code2000"))
