Your initial assertion regarding the codepoint would appear to no longer 
be correct based on the version of the font I have:

%%%%
\version "2.19.83"

#(format #t "~:{\n~a = ##x~x~}"
  (let ((font (ly:system-font-load "emmentaler-20")))
    (map (lambda (x)
           (list x (ly:font-glyph-name-to-charcode font x)))
         '("clefs.G" "clefs.tenorG_change"))))
%%%%

====
GNU LilyPond 2.19.83
Processing `glyphname.ly'
Parsing...
clefs.G = ##xe176
clefs.tenorG_change = ##xe17b
Success: compilation successfully completed

Consider using \musicglyph to look up a glyph by name instead of futzing 
with codepoints.
