BibTeXu: a Unicode compliant version of BibTeX
======================================================================

BibTeXu is the Unicode-compliant version of BibTeX, that reads (only)
UTF-8 encoded files.  It was written by Yannis Haralambous and his
students of Télécom Bretagne.

New features in this tool include:
  * UTF-8 compatibility of Unicode encoding
  * integration of sort and case-change routines from the ICU library
  * dependency on Unix locale (which can also be indicated manually
    through a command line option)

In less technical terms, BibTeXu allows the processing of
bibliographic references in all scripts of the world while leaving
some flexibility in the method of sorting and changing of case.

The first release of BibTeXu (sources + precompiled binaries) was
dated on 2009-09-23, which appeared on the website by Yannis [1].
It was later presented at Journée GUTenberg, a conference in France,
on 2009-11-21 [2, 3].

Status of BibTeXu in TeX Live
=============================

BibTeXu has been integrated into TeX Live 2010.
The one shipped with TL is updated so that BibTeX, BibTeX8 and BibTeXu
share more or less the same behavior wrt memory allocation, etc.
Peter Breitenlohner put in the massive efforts needed to make this
work in the TL build system and use the same ICU library as XeTeX.

Despite of that, it is likely that BibTeXu shipped with TL still does
not behave as expected.  The precompiled binaries of the first release
by Yannis on 2009-09-23 seemed to work to some extent, so there might
have been some inconsistency in the integration.

The files in examples/ show the expected behavior:
  * test.tex: the input XeLaTeX source, which uses a Unicode font
              covering Latin, Greek and Chinese
  * test.bib: the input BIB file
  * test.bbl: expected output of BibTeXu
              (obtained from BibTeXu 2009-09-23 with ICU 4.2.1)
  * test.pdf: expected final output of XeLaTeX

Hope that this works in the future.
