Wide Character String Operation Functions

Internationalization (I18n) Issue:

These functions operate upon strings composed with wide characters of type wchar_t *. These functions often replace single character string operations functions as a result of internationalization reengineering. To operate correctly, the underlying wchar_t * type must be properly implemented.

I18n Solution:

Use the appropriate equivalent wide character string function when reengineering an application for internationalization to correctly accommodate wide character string arguments.

I18n Discussion:

Wide character manipulation functions handle unique code point values for each character in the character set as specified by the compilation environment. For an internationalized application using the UTF-16 or UCS-2 Unicode character sets, the wchar_t * has a size of 16 bits.
