Replication Server supports all Sybase-supported character sets and perform character-set conversion of data and identifiers between primary and replicate sites. Character sets must be compatible for character-set conversion to be successful. For example, single-byte character set data cannot be converted to a multibyte character set. For details about character-set compatibility, see the Adaptive Server Enterprise System Administration Guide Volume 1.
Your choice of a character set for a given server is influenced by the languages the server supports, the hardware and operating system it runs on, and the systems with which it interacts.
These things are true of Sybase-supported character sets:
They are all supersets of 7-bit ASCII.
Some are completely incompatible with each other, meaning that they have no characters in common beyond 7-bit ASCII.
Among compatible character sets, some characters are not common to both sets—that is, no two character sets have all the same characters.
To change the default character set, follow the procedure provided in “Changing the character set and sort order”. Although changing the default character set requires only changing the value of the RS_charset parameter in the Replication Server configuration file, follow the steps provided in the procedure to ensure that no replicate data is corrupted by the change.
