Hi Tristan,

this feature request seems simple to implement on one side. However, it opens a question how to deal with those in general. 
\ruby{東} is a very specific command of the CJK package. 
If this get's implemented in the standard html exporter, other very special commands might need to follow. That could easily go into a nightmare. I do not have a detailed view how the exporters work now, thus, it is a interesting question I want to ask here: How should specific needs for exporting (like Tristans) be embedded in the future. 

People could fork exporters. Creating e.g. a HTML-CJK exporter.
Even better would be to have exporter modules which could be loaded by users. 

#+HTML_MODULES CJK, 

However, I believe that for many users, the special cases are not very frequent and complex. Might it be possible to create a very simple syntax for exporting rules which could be either in those above modules or directly within the file written by the user themself?
  
#+HTML_USER_RULE   \ruby{$1}{$2}, <ruby> $1 <rp>(</rp><rt>$2</rt><rp>)</rp> <\ruby>

Would like to hear what other think about that.

Greetings

Torsten

Hi,

So this is my first try to post to the mailing list. I Love Orgmode, you guys are the best!

I would like to use orgmode to capture japanese text to later export to latex, html and epub.
For japanese symbols, sometimes the pronounciation is put in smaller letters above the symbol to help the reader.
These are called ruby in general in typesetting (in japanese, they are also called furigana/yomigana, which I put in the header so not everybody thinks of the programming language..)
http://en.wikipedia.org/wiki/Furigana

In Latex, using CJK and ruby packages, This exports ok.
(A problem being that japanese text in headers doesn't. But i guess that's another (and rather Latex, not orgmode-specific) topic.

Now, my feature request would be to make the html exporter interpret the latex command
\ruby{symbol}{reading}
as:
<ruby> symbol <rp>(</rp><rt>reading</rt><rp>)</rp> <\ruby>

as suggested here, for parentheses on non-ruby supporting browsers:

For the org-mode file (you might see some blank squares if you have no japanese support):
Here a minimal working example for export:

###
#+LATEX_HEADER: \usepackage[CJK, overlap]{ruby}
#+LATEX_HEADER: \usepackage{CJK} \end{CJK}
#+LATEX \begin{CJK}{UTF8}{min}

"\ruby{東}{ひがし}アジア" means east asia in japanese
#+LATEX \end{CJK}
###


All the best, and keep on rocking my world in plain text! =)
