[XeTeX] Issue with CJK in pdf build

[Chris Jones]

I've already tried the docbook-app and dblatex lists and haven't been
able to clarify this issue so maybe someone here may have some idea how
I could address this.

I have a bare-bones DocBook xml file that contains:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE article PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN" "http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd">

<article>
<articleinfo>
    <title>Unicode blocks</title>

<section id="_cjk">
<title>CJK</title>
<para>Some CJK:</para>
<para>
㺀   㺁   㺂   㺃   㺄   㺅   㺆   㺇   㺈   㺉   㺊   㺋   㺌   㺍   㺎
㺏   㺐   㺑   㺒   㺓   㺔   㺕   㺖   㺗   㺘   㺙   㺚   㺛   㺜   㺝
㺞   㺟   㺠   㺡   㺢   㺣   㺤   㺥   㺦   㺧   㺨   㺩   㺪   㺫   㺬
㺭   㺮   㺯   㺰   㺱   㺲   㺳   㺴   㺵   㺶   㺷   㺸   㺹   㺺   㺻
㺼   㺽   㺾   㺿   㻀   㻁   㻂   㻃   㻄   㻅   㻆   㻇   㻈   㻉   㻊
㻋   㻌   㻍   㻎   㻏   㻐   㻑   㻒   㻓   㻔   㻕   㻖   㻗   㻘   㻙
</para>
</section>
</article>

The last <para> </para> above should contain a sample of CJK glyphs
starting at U+3e80 that should be visible with the adhoc font.

No particular reason why I chose CJK, same thing happens with math
symbols, arrows, etc.

I have tried building a pdf with this command:

-------------------------------------------------------------
$ dblatex -v -b xetex cjk0.xml

'cjk0.pdf' successfully built
-------------------------------------------------------------

There are no catastrophic errors and the cjk0.pdf is built, but when I
use evince or xpdf to visualize, all I see is the dreaded empty
rectangles.

I was under the impression that xetex used fontconfig and I do have at
least one font installed and defined to fontconfig (gnu-unifont) that
has the corresponding glyphs but it looks like I need to tell xetex
where to look for it.

I haven't seen anything in the dblatex doc that appears to deal with
fonts, so maybe there is a configuration file that I need to modify, but
I have no idea what/where it might be.

I did find a file at /usr/share/texmf-live/fonts/map/pdftex/ called
pdftex.map that lists what looks like a very large number of fonts, but
none looked familiar.

I also tried xmlto/xsltproc with identical results.

Also, this happens on a debian/lenny (stable) system and there is always
a chance that the packages that are installed are not current.

I admit that I'm quite confused with where xetex fits into the picture
but I have a feeling I'm just missing something pretty simple and
hopefully someone will be able to give me a push in the right direction.

Thanks,

CJ
