bibtex8 - 8-bit Big BibTeX


bibtex8 [options] aux-file


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.

-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

-v --version
