When clients and servers use different character sets, conversion between the character sets is necessary. Open Client/Server products include files to support conversions for the Group 1 (Western European) character sets.
The conversion files for a character set include:
A conversion description file, charset_name.cvt, which contains a user-readable character set mapping table for a conversion.
A conversion table loading file, charset_name.ctb. This file is used during Sybase’s internal table-driven conversion process. An internal program generates this file based on information in the Conversion Description File (charset_name.cvt).
A conversion configuration file, charset_name.cfg. This file contains information on how the conversion process should proceed when charset_name is the source character set.
