[pdftex] Unicode

[Fabrice Gadaud]

       Hi!

I'm developing some tools to automatically great a book from a blog. I'm
currently focused on Livejournal and I'm operating a free service:
http://www.ljbook.com .

Blogs are encoded in UTF-8 and I use the fine UCS package to handle this
with pdfLaTeX.
So my preambule includes:
\usepackage[autogenerated, warnunknown, fasterrors, privatecsur,
tipa]{ucs}
\usepackage{autofe}
\usepackage[utf8]{inputenc}

My goal is to handle any character with a wide range of fonts. So here
are my questions:
        - how to generate a PDF with various characters sets ? (Russian
characters, Latin, CJK, BIG5 ?!) Do I put \usepackage[T1, OT4,
...]{fontenc} ?
        - do I have to use an UNICODE font if I want all characters to
be displayed properly ? (Currently AReader tells that it can't find the
character in a dictionnary).

Thanks for any help!
