Use this parameter to tell BibDB what code page your computer is using.
Currently supported are code pages 437 (United States) and 850 (multilingual).
If you specify autodetect BibDB will retrieve the code page from DOS.
The code page is used in the 8-bit characters support, and in several other
minor places for cleaner displays. You might set the codepage parameter to a
setting other than your current code page if you are converting a file to
or from 8-bit format which does not fit your code page. Setting
codepage{none} will disable automatic 8-bit support.
