No, that unfortunate property (that particularly affects the mbrtoc32 function and was the reason why we introduced the 'mbrtoc32-regular' module). It is a problem with the BIG5-HKSCS encoding, not with the GB18030 encoding. (Recall that GB18030 is more-or-less a Unicode transformation format like UTF-8, UTF-16, UTF-32.)

Look for the GNULIB_MBRTOC32_REGULAR tests in the code... Bruno
