| 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{c32isblank}, provided by Gnulib module |
| @code{c32isblank}, operates on 32-bit wide characters and therefore does not |
| have this limitation. |
