ox-odt caption handling is more complex because it handles more elements
(e.g., links to ODF files). ox-ascii provides the bare minimum wrt
caption numbering. This is what your patch provides.

Of course, you're right. I realized that just after sending the message.
Though, in the following snippet,

  (setq caption-predicate
        (if (org-element-property :caption destination)
   	 (lambda (elem &optional info)
   	   (org-element-property :caption elem))
          (lambda (elem &optional info)
           (not (org-element-property :caption elem)))))

I suggest to drop the "else" part. If destination hasn't got any
caption, numbering doesn't make much sense anyway. You can re-use
`org-html--has-caption-p'.

:utf-8 will be used for ODT export and UTF-8 export. LaTeX export will
try to use, in this order, :latex, :default and "Figure %d:". Plain
ASCII will use, in this order, :ascii, :default and "Figure %d:".

I suggest to use a simple entry for :default, maybe romanji, if it makes
sense. You can also use UTF-8 encoding as :default, and provide some
meaningful translation for :ascii.

Thank you.
