Unicode Functions Supported

The IBM Informix ODBC Driver supports both ANSI and Unicode version of all functions that accept pointer to character strings or SQLPOINTER in their arguments. The following table describes the two types of functions supported:

ODBC "A" functions

These are the normal ODBC functions that accept single byte (ASCII) data as input for all the character/string parameters.

ODBC "W" functions

These are the Unicode functions that accept "wide characters" as input for all character/string parameters.

The ODBC specification defines these functions using the wchar_t data type. This is the standard C library wide character data type.

The following Unicode "wide" functions are supported by the IBM Informix ODBC Driver:
