I've eventually found out what zw stood for. It looks like an  
equivalent to em but refers to a square in which the letter is rather  
than to the letter itself...

So, after searching a little bit more today, I eventually found a  
number of very interesting related papers on the web:

Typesetting CJK languages with Omega (2004)

pTEX and Japanese Typesetting (2008)
(Okumura suggests _not_ using upTeX though.)

Also, thanks to the last issue of PracTeX Journal, I found this recent  
French book where the concept of boxes is explained in great details:

« Tout ce que vous avez toujours voulu savoir sur LaTeX sans jamais  
oser le demander »

So, I now understand a little bit what the sfkanbun.sty file is about  
but it is definitely way beyond my abilities to redefine sw so that it  
fits XeTeX.

I've eventually resorted to ask for advice on Mr. Okumura's Japanese  
TeX forum and I'm sure I'll have more information so that I can  
proceed with my book.


I'll report here when I have something concrete.
