bibtex8 - 8-bit Big BibTeX

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.

BibTeX8  was  written by Niel Kempson and Alejandro Aguilar-Sierra. It is currently maintained as part of
       TeX Live.

       This manpage was written for TeX Live, based on the work by Norbert Preining for Debian GNU/Linux.

bibtex8 4.00                                    12 September 2022                                     BIBTEX8(1)

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  output  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 characters.

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

       -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.

       -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).
