 Msearch 查询内容unsigned short 转化字符串输出  把网上能查的都查了，还是没找到，终于在网友棋剑千秋的帮助下，再次表示感谢，解决了这个问题终于可以大喘一口气了

}

调用

 int len=128*2;

    char cInfo[128] = {0};

    memset(cInfo, 0, sizeof(cInfo));

    UnicodeToUTF8((unsigned char*)cInfo,len,(info->pPois)->cName);

    NSString *poiName = [NSString stringWithUTF8String:cInfo];
