Re: [docbook-apps] Japanese Docbook/XML to PDF conversion trouble

Francois,

Did you try:  

    <xsl:output encoding="UTF-8">
or 
    <xsl:output encoding="Shift_JIS">

This has worked for me in going from
UTF-8 encoded Japanese DocBook documents > via xsltproc > FO >
via XSLCmd > PDF.

XSLCmd is a product of Antenna House:

I don't have any experience with dblatex.

You get that with dblatex, see below my comments.

The problem is that the XSLT processor is converting the UTF-8
characters of your source file into numeric entities, which left as is
would result into an invalid LaTeX file. dblatex assumes you want them
to appear on the final document, so it escapes them.
Either you find a way to convert those entities into the right LaTeX
commands; that would be an intermediate step between the XSLT processing
and the LaTeX run. Not that easy.
Otherwise you tell your XSLT processor to encode the output in UTF-8, so
that the Japanese characters appear as is instead of being converted
into entities. dblatex should already be configured to handle such
characters nicely.
In any case you should find help on dblatex-related mailing lists, where
I'm sure the problem has already been raised (and solved).

This is because you haven't configured FOP to use the rights fonts. It
will fall back to the default base-14 fonts for PDF, which don't contain
any glyphs for Japanese characters. Using any truetype font containing
Japanese glyphs should work, see here how to configure them:
http://xmlgraphics.apache.org/fop/0.20.5/fonts.html#truetype-metrics
If you have trouble you can get further help on the fop-users mailing list.
And BTW, you should really try the latest FOP 0.93 version which handles
DocBook documents much better...

Well, you better forget db2latex, which is no longer maintained and has
been superseeded by dblatex. Anyway you would face the same entities
issues as for dblatex.

The default LaTeX distribution from Debian should work.
