The problem may be a general one concerning org-beamer-environments-extra.
Any portion of the document containing Chinese characters should be
enclosed within a CJK environment. Reading ox-beamer.el, I see that I
can customize Org Beamer Environments Extra. After customizing, C-h v
org-beamer-environments-extra shows me:
((CJK Z \\begin{CJK}%a%h \\end{CJK}))
... snip
Whoa, wait a minute... it has completely omitted the CJK environment!
OK, after a bite for lunch, I see what the problem is.
The CJK environment, in the LaTeX code, must be specified with all
capital letters. (I tried changing the simple test file to say
\begin{cjk} and LaTeX failed, complaining of an unknown environment.
The test file does include \usepackage{CJK} and it works with
\begin{CJK} so the lowercase definitely means misspelled here.)
The Beamer exporter assumes that environment names will be all lowercase:
;; Use specified environment.
(t (downcase env)
I added my entry into org-beamer-environments-extra with the name
CJK -- so, when org-beamer-- format-block looks up the environment's
formatting spec according to the down-cased name cjk, it finds
nothing and then does not render the environment. But, if I were to
name the environment-extra as cjk, then the exporter would write
\begin{cjk} which I've already found will break.
I will temporarily work around the problem by removing downcase.
That should get me going for the slides I need to prepare today and
tomorrow. But there must be a more elegant solution. I'm not sure what
that is, but I am certain that it is not safe to assume environments
will always be named using only lowercase letters.
One more reason to fix: There is one out-of-the-box environment,
noteNH, which includes capital letters in the name. This one is also
broken -- does not appear in the output. I.e., you can encounter the
bug without customizing anything.
