  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{c32tob}, provided by Gnulib module
  @code{c32tob}, operates on 32-bit wide characters and therefore does not have
  this limitation.
