Conversion Within a Code Set

The multibyte conversion functions are similar to the one-byte conversion functions toupper() and tolower(). These functions convert wide-characters to other wide characters. For more information on conversion routines, see the man pages for wconv(3) for all locales and hconv(3) for Traditional Chinese.

The routines listed in the following table are in the regular Chinese C library:
