I get the following when connecting to Sybase ASE with the JConnect driver:
JZ006: Caught IOException: java.io.IOException: JZ0I6: An error occured converting UNICODE to the charset used by the server. Error message: java.io.CharConversionException: java.io.UnsupportedEncodingException: hp-roman8
The solution is to set a driver property (in the Properties tab for the connection):
charset = iso_1
