## 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 
              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 
              use language LANG to convert strings to low case.  This argument is passed to ICU  li‐
              brary.

### -o  --location 
              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.
