Asian Application Developer's Guide

Asian Locale-Specific Utilities

These utilities test various aspects of the Korean or Chinese national standard character sets. Except Korean isksc, they also assume that the character being tested is part of the national standard character set:

Korean: KS C 5601
Traditional Chinese: CNS 11643
Simplified Chinese: GB-2312-80

The arguments for the functions in these tables must be a character in WC, wchar_t. For more information, see the appropriate man page for your locale:

Korean--kctype(3x)
Simplified Chinese--cctype(3x)
Traditional Chinese--hctype(3x)
