## NAME
       bibtex8 - 8-bit Big BibTeX

## SYNOPSIS
       **bibtex8 **[_options_] _aux-file_

## DESCRIPTION
       **BibTeX8  **is  an  8-bit implementation of BibTeX written in C.  It has been enhanced by adding
       the following features:

       - "big" (32-bit) and customisable capacity

       - flexible support for non-English languages using 8-bit character sets

       **BibTeX8 **accepts 8-bit characters in its input files, and writes 8-bit characters to its  out‐
       put  files.   The character set is defined by an external configuration file --- the Codepage
       and Sort order ("CS") file.  By default, it reads a specific CS  file  "88591lat.csf",  which
       defines  ISO 8859-1 character set and its alphabetical sorting order including accented char‐
       acters.

## OPTIONS
### -?  --help
              display some brief help text.

### -7  --traditional
              operate in the original 7-bit mode, no CS file used.  Only 7-bit ASCII characters  are
              supported, and they are sorted by ASCII code value.

### -8  --8bit
              force  8-bit  mode, no CS file used.  All 8-bit characters (code > 127) are treated as
              letters, and they are sorted by their code value.

### -c  --csfile 
              read FILE as the BibTeX character set and sort definition file.  Note that options **-7**,
              **-8 **and **-c **are exclusive.

### -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.

### -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 ##.

       **--mcites **##
              allow ## \cites in the .aux files (deprecated).

       **--mentints **##
              allow ## integer entries in the .bib databases (deprecated).

       **--mentstrs **##
              allow ## string entries in the .bib databases (deprecated).

       **--mfields **##
              allow ## fields in the .bib databases (deprecated).

       **--mpool **##
              set the string pool to ## bytes (deprecated).

       **--mstrings **##
              allow ## unique strings.

       **--mwizfuns **##
              allow ## wizard functions (deprecated).


**8BIT LATIN LETTERS SUPPORT**
       **BibTeX8 **supports extended features to handle 8bit latin letters.  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.

       **chr.to.int$**, **int.to.chr$**
              The function is the same as original BibTeX but 8bit characters are accepted.

       **width$ **The function is the same as original BibTeX but letters of Latin-1 are supported.
