error: Non-hex digit used for Unicode escape

[Charlie Turner]

Hello,

Running Windows Vista 64 bit, service pack 1
GNU Emacs 22.2.1 (i386-mingw-nt6.0.6001)

I get the above error message in my *Messages* buffer on startup. Here
is the version I get when I run "runemacs.exe --debug-init":

Debugger entered--Lisp error: (error "Non-hex digit used for Unicode escape")
  eval-buffer(#<buffer  *load*> nil
"c:/Users/Charles/.emacs.d/init.el" nil t)  ; Reading at buffer
position 46
  load-with-code-conversion("c:/Users/Charles/.emacs.d/init.el"
"c:/Users/Charles/.emacs.d/init.el" t t)
  load("c:/Users/Charles/.emacs.d/init" t t)
  #[nil "พ

(setq default-directory "C:\Users\Charles")
(setq inhibit-startup-message t)
(fset 'yes-or-no-p 'y-or-n-p)
(setq make-backup-files nil)

Thank you for your time.
