libiconv.lib and iconv.h for win64

编码转换的64包，我是在jni封装ctp时使用这个传中文可以不乱码 int code_convert(const char *from_charset, const char *to_charset, char *inbuf, size_t inlen, char *outbuf, size_t outlen) { iconv_t cd; int rc; char **pin = &inbuf; char **pout = &outbuf; cd = iconv_open(to_charset, from_charset); int argument = 1; if (cd == 0) return -1; if (iconv(cd,(char **)pin, &inlen;, pout, &outlen;) == -1) { iconv_close(cd); return -1; } iconv_close(cd); return 0; } #define GB2312TOUTF8FORCONTENT \ char result_utf8[1000]={0}; \ if(result) \ { \ unsigned int inlength=strlen(result); \ int rsp=code_convert("gb2312","utf-8",result,inlength,result_utf8,1000);\ if(rsp!=-1) jresult = jenv->NewStringUTF((const char *)result_utf8);\ }
