Emacs versions other than the emacs-unicode-2 branch store each of the
iso-8859-x glyphsets separately.  You are probably ending up with the
8859-1 (Latin 1) version of U+00E7 LATIN SMALL LETTER C WITH CEDILLA
in the elisp; using the turkish-postfix input method most likely uses
8859-9 (Latin 5).  

One way to make latin1’s ç and latin5’s ç match is to use one or both
of unify-8859-on-decoding-mode and/or unify-8859-on-encoding-mode.

Or, make sure you use the same encoding to enter the elisp that your
users will use.  There are commands to convert the current buffer to
a different encoding.  

Since I’ve moved almost exclusively to the unicode-2 branch, I don’t
remember the specifics of the unify-8859 modes, but they are documented
in info.
