You're welcome, as always. (And it is nice to receive some of your
e-mails once in a while).

Great that this worked. I suspected that it would be the case.

I am trying to work with Michael, but it seems that my mails to him are
not getting through. :-) (Michael, let us join forces in this, pal).
A very simplified version of the facts is this: CJK fonts need way more
than the 256 different characters. Therefore, for backwards
compatibility, we have to jump through many hoops to map to make things
work. Part of that job is to map CID fonts to Unicode characters, use
CMaps etc.
To cut a long story short, you can install the xpdf-japanese package,
or, since you already have poppler-data installed, you can simply add
these lines to your .xpdf and see if things work:
,----[ .xpdfrc ]
| cidToUnicode Adobe-Japan1 /usr/share/poppler/cidToUnicode/Adobe-Japan1
| toUnicodeDir /usr/share/poppler/cMap/Adobe-Japan1/
| toUnicodeDir /usr/share/poppler/cMap/Adobe-Japan2/
| cMapDir Adobe-Japan1 /usr/share/poppler/cMap/Adobe-Japan1/
| cMapDir Adobe-Japan2 /usr/share/poppler/cMap/Adobe-Japan2/
`----
Please let me know if things work with that, as I am integrating support
to rich documents on the xpdf tree that I am starting to maintain. Some
extra lines may be needed, depending on how you have things installed.

Sure, I have been bitten by this problem many times in the past and I
did not know that there were some nasty patents in this.

Yes, even though poppler-data was non-free, it is now in main and I
don't know why it hasn't been added to recommends already.
