Unicode from Other ILE Languages
The Unicode functions are easily accessible in the C and C++ languages if you include the appropriate header files and use the appropriate LOCALETYPE option on the C or C++ compilation command. The Unicode functions are accessible from other ILE languages, such as RPG, COBOL, and CL, although no header files are provided for these languages.
The following table shows the functions added for UCS-2 support. The support functions have a
prefix of
_UCS2_ or _C_UCS2_ added to the standard function name.
The Unicode function has the same parameters as the standard (non-Unicode) function.

When you use the LOCALETYPE(*LOCALEUCS2) option with either the
C or C++ compiler, the default UCS-2 locale is loaded when the program
starts. When you use any of the Unicode functions in the preceding
table from a different language, a call to _UCS2_setlocale(LC_ALL,
"") should be added when the application starts to ensure that the
default UCS2 locale is loaded.
The following table shows the functions added for CCSID neutral
and UTF-8 support. The functions have a prefix of _C_NEU_DM_ (for
data management I/O functions), _C_NEU_IFS_ or _C_UTF_IFS (for
IFS I/O functions), or _C_NEU_ or _C_UTF_ added
to the standard function name. The Unicode function has the same parameters
as the standard (non-Unicode) function.
Functions that operate on wide characters have
UTF in the prefix. Functions that
do not operate on wide characters have NEU in the prefix.
