I got following error in *Messages* buffer:

#+begin_example
caution: filename not matched:  \·\¥\°\Ÿ1-3\ -\ \”\º\¾\·\‡\ -\ 1.jpg

(New file)
#+end_example

Aha, really encoding issue, because Emacs minibuffer echo-area only displayed "(New file)", so I
have not noticed this error. My fault. I should check this buffer. Thanks for point it out.

Is there a method to solve this problem? How to know the filename coding? And how to let Emacs auto
decide which coding for filename?
