I used to have problem on open Org Mode file link with external program.

The detailed check out this mail thread archive:

https://orgmode.org/list/87a717ggsr.fsf@nicolasgoaziou.fr/T/#maaf63fde8eefeb5ebbaa3e6f53bc88db686878ed

And later I found this link:

https://askubuntu.com/questions/646631/emacs-doesnot-work-with-xdg-open

I realized the problem might on Emacs itself. Then I did an test:

#+begin_src emacs-lisp
(let ((cmd (format
            "%s %s"
            "xdg-open"
            (shell-quote-argument
             (expand-file-name
              "~/Downloads/伦敦底层社会 1，2章.doc")))))
  (start-process-shell-command cmd "*org-open-file*" cmd))

(start-process "org-open-file"
               " *org-open-file*"
               "xdg-open"
               (expand-file-name "~/Downloads/伦敦底层社会 1，2章.doc"))
#+end_src

Both of upper code snippet failed.

Can someone explain this problem on ~start-process~ and
~start-process-shell-command~ more detailed?

And is there any solution, or this is a bug?

Thanks for viewing my problem. Regards.
