UNICODE十六进制的数组转成中英文

实现char*转换成中英文，每两个char合成一个wchar_t：

// UNICODE十六进制数组转成中英文// hex array to wchar_t*// wchs == NULL, wchsLen as output(the size of wchs will be used)// error: return -1int YCodec::HexArray2WChars(char* hexarry, int hexarrylen, wchar_t* wchs, int* wchslen){if(hexarry == NULL || hexarrylen<=0)return -1;if(wchs == NULL){*wchslen = hexarrylen/2 + (hexarrylen%2==0 ? 0 : 1);return 1;}memset(wchs, 0, *wchslen * sizeof(wchar_t));char tmp[3];char* phex = hexarry;wchar_t* pwchs = wchs;for(int i=0; i<hexarrylen; i++){memset(tmp, 0, 3);tmp[0] = *phex++;if(++i >= hexarrylen)break;tmp[1] = *phex++;// two char to a hexunsigned short hex = 0x0;hex = (tmp[0] & 0xff) << 8;hex |= tmp[1] & 0xff;// hex to wchar_t*pwchs++ = (wchar_t)hex;}return 1;}

调用实例：

//wchar_t* unicode = NULL;char ascii[] = {0x62, 0x4b, 0x67, 0x3a, 0x53, 0xf7, 0x4e, 0x3a,0x00, 0x31, 0x00, 0x38,0x00, 0x38, 0x00, 0x38,0x00, 0x37, 0x00, 0x36,0x00, 0x35, 0x00, 0x35,0x00, 0x32, 0x00, 0x31,0x00, 0x30, 0x76, 0x84};int wchslen = 0;YCodec yCodec;// hex array to wchar_t*if(yCodec.HexArray2WChars(ascii, 32, NULL, &wchslen) != -1){wchar_t* wchs = new wchar_t[wchslen+1];memset(wchs, 0, sizeof(wchar_t)*(wchslen+1) );int n = yCodec.HexArray2WChars(ascii, 32, wchs, &wchslen);if(n != -1){// wchar_t to CStringCString tmp;wchar_t * pwch = wchs;for(int i=0; i<wchslen; i++)tmp.AppendChar(*pwch++);m_Disp.SetWindowTextW(tmp);}delete []wchs;}

在MFC程序中测试通过。

已实现把0x62, 0x4b, 0x67, 0x3a, 0x53, 0xf7, 0x4e, 0x3a, 0x00, 0x31, 0x00, 0x38, 0x00, 0x38, 0x00, 0x38, 0x00, 0x37, 0x00, 0x36, 0x00, 0x35, 0x00, 0x35, 0x00, 0x32, 0x00, 0x31, 0x00, 0x30, 0x76, 0x84这一串unicode的十六进制字符数组转成中英文。

结果为：

手机号为18887655210的

基本测试通过，暂未发现神马问题。
