--- Comment #1 from Gerard Zagema <forum at emblocks dot org> ---
I think (works for me) that in valprint.c in the function generic_printstr the
make_wchar_iterator gets the original string length and not modified by c-style
terminators. I did the following:

// NOTE (Gerard#1#): Remember original length ('i' is not used here)
i= length;

  /* If the string was not truncated due to `set print elements', and
     the last byte of it is a null, we don't print that, in
     traditional C style.  */
  if (c_style_terminator
      && !force_ellipses
      && length > 0
      && (extract_unsigned_integer (string + (length - 1) * width,
                    width, byte_order) == 0))
    length--;

  if (length == 0)
    {
      fputs_filtered ("\"\"", stream);
      return;
    }

  /* Arrange to iterate over the characters, in wchar_t form.  */
// NOTE (Gerard#1#): replace length with original 'i'
  iter = make_wchar_iterator (string, i * width, encoding, width);
