Dired does not correctly process file names with ornamented and special Characters in Emacs for Windows

Hello

 

Filenames with ornamented or special characters are often not shown correctly in "dired", and cannot be opened. The strange thing is: sometimes it works properly, but I cant figure out under what circumstances - it seems to be completely arbitrary. Would anybody know how to make it always work ?

 

Im on Windows 7-64bit, running a Emacs Version 25.0.50.1 (x86_64-w64-mingw32) of 2015-11-10, which I downloaded from http://sourceforge.net/projects/emacsbinw64/?source=typ_redirect 

 

I additionally installed msys2-64bit with mingw64, which is included in my Windows environment variable PATH (...;C:\Programme\msys2-64\mingw64\bin)

 

Based on information I found on the web, I further added the following to my init.el file:

 

;; configure grep acc to http://jpstup.blogspot.ch/2011/02/getting-emacss-rgrep-working-in-windows.html 

;; and http://www.gnu.org/software/emacs/manual/html_mono/efaq-w32.html#Dired-ls 

 

(when (or (eq system-type 'windows-nt) (eq system-type 'msdos))

      (setenv "PATH" (concat "C:\\Programme\\msys2-64\\usr\\bin;C:\\Programme\\msys2-64\\mingw64\\bin;" (getenv "PATH")))

      (setq ;;find-program "C:\\Programme\\msys2-64\\usr\\bin\\find.exe"

            ;;grep-program "C:\\Programme\\msys2-64\\usr\\bin\\grep.exe"

            ls-lisp-use-insert-directory-program t      ;; use external ls

            insert-directory-program "c:\\Programme\\msys2-64\\usr\\bin\\ls.exe" ;; ls program name

                    diff-command "C:\\Programme\\msys2-64\\mingw64\\bin\\diff.exe"

      )

)

;; Prevent issues with the Windows null device (NUL)

;; when using cygwin find with rgrep.

(defadvice grep-compute-defaults (around grep-compute-defaults-advice-null-device)

"Use cygwin's /dev/null as the null-device."

(let ((null-device "/dev/null"))

ad-do-it))

(ad-activate 'grep-compute-defaults)
