- This option group includes functions for reading and writing
- wide characters to and from <stdio.h> streams.

- This option group includes the following functions:
-
- fgetwc fwprintf putwchar vwscanf
- fgetws fwscanf ungetwc wprintf
- fputwc getwc vfwprintf wscanf
- fputws getwchar vfwscanf
- fwide putwc vwprintf

- This option group further includes the following unlocked
- variants of the above functions:
-
- fgetwc_unlocked getwc_unlocked
- fgetws_unlocked getwchar_unlocked
- fputwc_unlocked putwc_unlocked
- fputws_unlocked putwchar_unlocked
-
- Note that the GNU standard C++ library, 'libstdc++.so', uses
- some of these functions; you will not be able to link or run
- C++ programs if you disable this option group.
-
- This option group also affects the behavior of the following
- functions:
-
- fdopen
- fopen
- fopen64
- freopen
- freopen64
-
- These functions all take an OPENTYPE parameter which may
- contain a string of the form ",ccs=CHARSET", indicating that
- the underlying file uses the character set named CHARSET.
- This produces a wide-oriented stream, which is only useful
- when the functions included in this option group are present.
- If the user attempts to open a file specifying a character set
- in the OPENTYPE parameter, and EGLIBC was built with this
- option group disabled, the function returns NULL, and sets
- errno to EINVAL.
