pdf with vertical text

I'm trying to transform a pdf to html file using 'pdftohtml' that contain
japanese langage.
Everything is fine with horizontal text but each generated div for vertical
text has width set to 0.

I tried to fix this and I have found this in following function
GfxCIDFont::getNextChar() :

...
  // vertical
  } else {
    w = 0;
...

and width doesn't seem to be updated later. So I have tried to do like in
horizontal mode :

...
  // vertical
  } else {
    w =getWidth(cid);
...

the result is good, all my divs have a width. Is it the right way ? 
(there is a pdf exemple on attachment)
