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.

@item

|
This function does not support the @code{"tolower"} and @code{"toupper"}
|
|
mappings on some platforms:
|
|
NetBSD 10.0.
|
|
(It returns non-null values for the arguments @code{"towlower"} and
|
|
@code{"towupper"}, but with these values, the function @code{towctrans}
|
|
always crashes.)

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.
|
|
@mindex c32_get_mapping
|
|
However, the Gnulib function @code{c32_get_mapping}, provided by Gnulib module
|
|
@code{c32_get_mapping}, operates on 32-bit wide characters and therefore does
|
|
not have this limitation.
