NAME

       bibtexu - UTF-8 Big BibTeX

SYNOPSIS

       bibtexu [options] aux-file

DESCRIPTION

       BibTeXu  is  the Unicode-compliant version of BibTeX.  It is largely based on Niel Kempson's BibTeX8, and
       it provides a better support for UTF-8 by integrating ICU library.  Therefore, BibTeXu no longer requires
       the Codepage and Sort order ("CS") file;  instead,  the  method  of  sorting  and  case-changing  can  be
       controlled via command-line options.

OPTIONS

       -?  --help
              display some brief help text.

       -d  --debug TYPE
              report debugging information.  TYPE is one or more of all, csf, io, mem, misc, search.

       -s  --statistics
              report internal statistics.

       -t  --trace
              report execution tracing.

       -v  --version
              report BibTeX version.

       -l  --language LANG
              use language LANG to convert strings to low case.  This argument is passed to ICU library.

       -o  --location LANG
              use language LANG for sorting.  This argument is passed to ICU library.

       -B  --big
              set large BibTeX capacity.

       -H  --huge
              set huge BibTeX capacity.

       -W  --wolfgang
              set really huge BibTeX capacity for Wolfgang.

       -M  --min_crossrefs ##
              set min_crossrefs to ##.

       --mstrings ##
              allow ## unique strings.

UNICODE SUPPORT

       BibTeXu  supports  extended  features  to  handle  Unicode  characters.   Several  built-in  functions in
       bibliography styles are enhanced as follows.

       &      Pops the top two (integer) literals and pushes their bitwise AND.

       |      Pops the top two (integer) literals and pushes their bitwise OR.

       add.period$
              Pops the top (string) literal, adds a `.' to it if the last non`}' character isn't a `.', `?', `!'
              or a Unicode punctuation mark and pushes this resulting string.  The mark may be  U+203C,  U+203D,
              U+2047, U+2048, U+2049, U+3002, U+FF01, U+FF0E or U+FF1F.

       chr.to.int$
              Pops  the top (string) literal, makes sure it's a multibyte string of a single Unicode code point,
              converts it to the corresponding Unicode scalar value (integer), and pushes this integer.

       int.to.chr$
              Pops the top (integer) literal, interpreted as the Unicode scalar value of a  single  code  point,
              converts it to the corresponding single character multibyte string, and pushes this string.

       num.names$, format.name$
              The function is the same as original BibTeX but an Ideographic/Fullwidth Comma (U+3001, U+FF0C) in
              addition  to  an  "  and " string is accepted as a separator between persons and Ideographic Space
              (U+3000) in addition to a space " " is accepted as a separator between a family name and  a  given
              name.

       substring$, text.length$, text.prefix$
              The function is the same as original BibTeX but the unit of operand numbers is Unicode code point.

       change.case$
              The  function  is the same as original BibTeX but letters of non-english Latin, Greek and Cyrillic
              are supported.

       width$ The function is the same as original BibTeX but letters of Latin-1 and Latin  Extended-A  and  CJK
              characters are supported.

       is.cjk.str$
              Pops  the  top  (string)  literal,  set flag bits to an integer if CJK characters are found in the
              string, and pushes the resulting integer, otherwise pushes 0.  Flags 0x001,  0x002,  0x004,  0x008
              and  0x800  are  corresponding  to  Hanzi  (Kanji,  Hanja),  Kana,  Hangul, Bopomofo and other CJK
              characters, respectively.  For example, an  integer  0x003  will  be  pushed  if  Hanzi  and  Kana
              characters are found in a poped string literal.

       is.kanji.str$
              Same as is.cjk.str$ for compatibility with (u)pBibTeX.
