The SAP ASE server stores data using its default character set, which is configured during installation. If your terminal does not support that default character set, it may send confusing characters to bcp when you respond to prompts either by typing or by using host file scripts.
The default is not necessarily the same character set that was configured for the SAP ASE server.
The default may not necessarily be the character set that the client is using.
For more information about character sets and the associated flags, see Configuring Client/Server Character Set Conversions in the System Administration Guide.
