Character set conversion is not available between client character set '%.*s' and server character set '%.*s'.
Character set conversion is the change of the encoding scheme of a set of characters on the way into or out of Adaptive Server. Conversion is used when Adaptive Server and a client communicating with it use different character sets. For example, if Adaptive Server uses character set ISO 8859-1 (ISO_1) and a client uses Code Page 850, character set conversion must be turned on so that both Adaptive Server and the client interpret data passing back and forth in the same way.
Error 2401 occurs when an invalid character set conversion is requested (for example, ASCII_8 with ISO 8859-1). When this error is raised, no conversion is performed.
Error 2401 can occur:
When a client requests a connection, Adaptive Server checks whether it can convert from the client’s character set to its own character set. If it cannot do the requested conversion because conversion is not available between the two character sets, this error is raised.
If you use the set char_convert command to start conversion between the Adaptive Server character set and a different character set and conversion for those character sets is not available, this error is raised.
Refer to the table “Supported languages and character sets” in the chapter “Configuring Character Sets, Sort Orders, and Languages” in the System Administration Guide: Volume 1 and check the table of valid conversion matches. Make sure you are not requesting conversions involving incompatible character sets. Consider using Unicode conversions to convert between incompatible character sets.
Character set conversion is only available for certain character sets. Valid conversion matches are listed in the System Administration Guide: Volume 1 in the chapter “Configuring Client/Server Character Set Conversions.”
