icd = (iconv_t) (-1) is not a valid conversion descriptor.

You must check the return value of the iconv_open() function.

You need to read the specifications of the iconv_open() and iconv() functions:
http://www.gnu.org/savannah-checkouts/gnu/libiconv/documentation/libiconv-1.13/iconv_open.3.html
http://www.gnu.org/savannah-checkouts/gnu/libiconv/documentation/libiconv-1.13/iconv.3.html
in particular the sections "RETURN VALUE" and "ERRORS".

It is not that easy to use iconv() correctly. If you want to convert
an entire string, you can use the convenience functions contained in the
'extras' directory of the GNU libiconv source distribution:
