10.71.65 wcswidth ¶
POSIX specification:
https://pubs.opengroup.org/onlinepubs/9799919799/functions/wcswidth.html
Gnulib module: wcswidth
Portability problems fixed by Gnulib:
- This function is missing on some platforms:
OpenBSD 3.8, Minix 3.1.8, mingw, MSVC 14.
Portability problems not fixed by Gnulib:
- On Windows and 32-bit AIX platforms,
wchar_t is a 16-bit type and therefore cannot
accommodate all Unicode characters.
However, the Gnulib function c32swidth, provided by Gnulib module
c32swidth, operates on 32-bit wide characters and therefore does not
have this limitation.
