  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{c32isalnum}, provided by Gnulib module
  @code{c32isalnum}, operates on 32-bit wide characters and therefore does not
  have this limitation.
  @end itemize
