@section @code{wcswidth}
@findex wcswidth
POSIX specification:@* @url{https://pubs.opengroup.org/onlinepubs/9699919799/functions/wcswidth.html}
Gnulib module: wcswidth
Portability problems fixed by Gnulib:
@itemize
@item
This function is missing on some platforms:
OpenBSD 3.8, Minix 3.1.8, mingw, MSVC 14.
@end itemize
Portability problems not fixed by Gnulib:
@itemize
@item
On Windows and 32-bit AIX platforms, @code{wchar_t} is a 16-bit type and therefore cannot
accommodate all Unicode characters.
However, the Gnulib function @code{c32swidth}, provided by Gnulib module
@code{c32swidth}, operates on 32-bit wide characters and therefore does not
have this limitation.
