I am so sorry.

I don't know where to modify the code that make DM800se can show right Chinese text EPG, but I know how to make GBK to UTF8 or UTF8 to GBK on Windows PC system. here is the example!

#include <iostream>
#include <string>
#include <fstream>
#include <windows.h>

using namespace std;

string GBKToUTF8(const std::string& strGBK)
{
string strOutUTF8 = "";
WCHAR * str1;
int n = MultiByteToWideChar(CP_ACP, 0, strGBK.c_str(), -1, NULL, 0);
str1 = new WCHAR[n];
MultiByteToWideChar(CP_ACP, 0, strGBK.c_str(), -1, str1, n);
n = WideCharToMultiByte(CP_UTF8, 0, str1, -1, NULL, 0, NULL, NULL);
char * str2 = new char[n];
WideCharToMultiByte(CP_UTF8, 0, str1, -1, str2, n, NULL, NULL);
strOutUTF8 = str2;
delete[]str1;
str1 = NULL;
delete[]str2;
str2 = NULL;
return strOutUTF8;
}

string UTF8ToGBK(const std::string& strUTF8)
{
int len = MultiByteToWideChar(CP_UTF8, 0, strUTF8.c_str(), -1, NULL, 0);
unsigned short * wszGBK = new unsigned short[len + 1];
memset(wszGBK, 0, len * 2 + 2);
MultiByteToWideChar(CP_UTF8, 0, (LPCTSTR)strUTF8.c_str(), -1, wszGBK, len);

len = WideCharToMultiByte(CP_ACP, 0, wszGBK, -1, NULL, 0, NULL, NULL);
char *szGBK = new char[len + 1];
memset(szGBK, 0, len + 1);
WideCharToMultiByte(CP_ACP,0, wszGBK, -1, szGBK, len, NULL, NULL);
std::string strTemp(szGBK);
delete[]szGBK;
delete[]wszGBK;
return strTemp;
}


Thank you very much!
