IBM i - iconv() - Unicode support enhancement (MS932 sequence)

Microsoft Unicode sequence support on iconv() is required.
IBM i provides single 1399<->Unicode converter which complies Unicode standard, not the same as Microsoft conversion table.
Thus, the result of conversion is different from 5035 (compatible to MS Unicode) and causes confusion to customers.

Academically correct but practically annoying.
Other IBM S/W products provide function or procedure to switch between IBM and MS.
- IBM i : incompatibility statement (Japanese)
- IBM i : PTF
- Db2 LUW
- Domino (Japanese)

Use Case:

Customer who (implicitly) use iconv() for 1399<->Unicode conversion see the same result as before (5035).

    The IBM default mapping support for CCSID 1399 to and from Unicode converts 5 characters differently than Microsoft does in its default support. This can cause problems for customers that have both operating systems in their environment. To help address this difference there is an additional map that will translate these 5 characters like Microsoft does. To access this conversion, specify a conversion alternative of 7 on the iconv_open() API.

    For more information on how to address this, see Alternative CCSID 1399 conversion in IBM i Documentation for release 7.5.
