It looks like this is a bug in iconv. Converting the attached source with `iconv -f utf-8 -t gb2312 testencoding.cpp` gives the same error. According to the GB2312 code table [1], the EM DASH symbol (U+2014) should map to the double-byte sequence `A1 AA`. There is no difference among GB2312, GBK and GB18030. Please consider GB2312 superseded by GBK. The native code page (936) references GBK instead of GB2312.
