Question

I have tried all of this:

Changing coding system:

(prefer-coding-system 'iso-latin-1-unix)

Ensuring no translation:

(add-untranslated-filesystem "C:")
(add-untranslated-filesystem "D:")

Setting multibyte characters to nil:

(custom-set-variables
  ;; custom-set-variables was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.
 '(desktop-save-mode t)
  '(enable-multibyte-characters nil))

None of this work for me.

I use Emacs 22.2.1 with Cygwin.

GNU Emacs 22.2.1 (i386-mingw-nt6.1.7100) of 2008-03-26 on RELEASE

Here’s how I start my emacs (remember %~dp0 puts the dirname of the executing file with path separator ) :

@set PATH=c:\cygwin\bin;%~dp0;%PATH%
@start %~dp0runemacs.exe %1 %2 %3 %4 %5 %6 %7 %8 %9
