Siddhesh Poyarekar 6e230d1183 Fix validation check when converting from ibm930 to utf
[BZ #14134]

When converting IBM930 code with iconv(), if IBM930 code which
includes invalid multibyte character "0xffff" is specified, then
iconv() segfaults. This is easy to see using the following command:

echo '0x0e 0x43 0x8c 0xff 0xff 0x43 0xbd 0x43 0xbd' | xxd -r |
	iconv -f IBM930 -t UTF-8
