10.72.33 wctrans ¶
POSIX specification:
https://pubs.opengroup.org/onlinepubs/9799919799/functions/wctrans.html
Gnulib module: wctrans
Portability problems fixed by Gnulib:
- This function is missing on some platforms:
Minix 3.1.8, HP-UX 11.00, mingw, MSVC 9, Android 7.1.
- This function does not support the
"tolower" and "toupper"
mappings on some platforms:
NetBSD 10.0.
(It returns non-null values for the arguments "towlower" and
"towupper", but with these values, the function towctrans
always crashes.)
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 c32_get_mapping, provided by Gnulib module
c32_get_mapping, operates on 32-bit wide characters and therefore does
not have this limitation.
