Description:
Provides functions to detect, translate, and map wide characters.
Wide characters are classified into the following types: alnum, alpha, upper, lower, digit, xdigit, graph, cntrl, punct, and space. You can use these functions to detect the type of wide characters and translate the type for the current locale LC_CTYPE or a specified locale. You can use these functions to convert the case of wide characters, map the wide characters, and obtain the mapping descriptor for conversion.
