z/OS® support for the Unicode Standard provides support that allows the normalization (decomposition or composition) of Unicode characters to one of the normalization forms. For a detailed explanation of normalization, including specific information about the normalization forms, refer to the Technical Report #15 provided by the Unicode Consortium (http://www.unicode.org/unicode/reports/tr15/).

The normalization service is called using a stub routine named CUNLNORM for AMODE (31) or CUN4LNOR for AMODE (64).
