An Internet Assigned Numbers Authority (IANA) value. You must specify a value for this option if your application is not Unicode enabled or if your database character set is not Unicode.
The driver and Driver Manager both check for the value of IANAAppCodePage in the following order:
In the connection string
In the Data Source section of the system information file (odbc.ini)
In the ODBC section of the system information file (odbc.ini)
If the driver does not find an IANAAppCodePage value, the driver uses the default value of 4 (ISO 8859-1 Latin-1).
Valid Values

is a valid IANAAppCodePage value. The value must match the database character encoding and the system locale. For a list of valid IANAAppCodePage values, refer to IANAAppCodePage Values in the Progress DataDirect for ODBC Drivers Reference.
