Converts multi-byte string data to Universal Character Set (UCS).
int cciMbsToUcs( int* returnCode, const char* mbString, CciChar* ucsString, int ucsStringLength, int codePage);
For an ASCII system, a value of 1208 (meaning code page ibm-1208, which is UTF-8 Unicode) is a good choice if you are using cciMbsToUcs to convert string constants for processing by WebSphere® Message Broker. 1208 is appropriate for Linux and UNIX, and for Windows platforms.
On Linux and UNIX, nl_langinfo(CODEPAGE) gives you the code page that has been selected by setlocale.
For OS/390 and z/OS, the default code page for WebSphere MQ, which is 500, should not be used. Instead, you should use a code page value of 1047.
