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.
