Dear list,

I'm trying to set up Mobile Org, but there's some problem,

All my org files are placed in in ~/My Dropbox/org/org, as following:
-----
(defvar org-dir (concat Dropbox "/org") "org dir")
(defvar org-source-dir (concat Dropbox "/org/org")  "org source dir")
(defvar pub-html-dir (concat Dropbox "/org/public_html") "html dir")
(defvar org-mobile-dir (concat Dropbox "/MobileOrg") "org mobile dir")

Then I set Mobile Org like this:
(setq org-mobile-directory org-source-dir)
(setq org-mobile-force-id-on-agenda-items nil)
(setq org-mobile-inbox-for-pull (concat org-source-dir "/mobile.org"))

After org-mobile-push command, the agenda is generated, but in Mobile Org,
it could not be opened,
and the error message is bad file encoding, unable to detect file encoding,
please re-save this file using UTF-8.

So how could I figure out what the file encoding of my org files, and if
not, how to convert them (there's quite a bit) to UTF-8,
and in the future how to save the files automatically to UTF-8 with the
Chinese support?

The coding system is really confusing, thanks a lot!!
