Ah, OK.  Those coding keys are for the back-ends to select proper
strings, not for the string encoding.

Then, is there any restriction with HTML back-ends? Why does it need
numeric character reference instead of just plain characters, if the
coding system is not a concern?

Correct me if I'm wrong.  My understainding is as follows: All
translation strings is in `emacs-internal' coding system, since it is
defined in .el.  A org file ready to be exported has a coding system
specific to the buffer, ie. utf-8, iso-latin-1, euc-jp, etc.

Org export back-ends get a strings for the back-ends from the
translation table when appropriate.  At that time Emacs converts the
strings encoding system to match the buffer encoding system (or does
Emacs convert all encoding when it writes to file?).  Back-ends uses
`org-export-coding-system' if set, otherwise use the current buffer
coding system.


If my understanding is ok, all entries of Japanese translation should
have :default instead of :utf-8.

Thanks,
