字符格式相互转换：Unicodeansi utf8

int Unicode2UTF8(const wchar_t* pUnicode, char* pUTF8Buffer, int nBufferSize) { if( (nBufferSize == 0) && (pUTF8Buffer != NULL) ) return 0; int result = WideCharToMultiByte(CP_UTF8, NULL, pUnicode, -1, pUTF8Buffer, nBufferSize, NULL, NULL); if ((result > 0) && (pUTF8Buffer != NULL)) pUTF8Buffer[result-1] = 0; return result; } int UTF82Unicode(const char* pUTF8, wchar_t* pUnicodeBuffer, int nBufferSize) { if( (nBufferSize == 0) && (pUnicodeBuffer != NULL) ) return 0; int result = MultiByteToWideChar(CP_UTF8, NULL, pUTF8, -1, pUnicodeBuffer, nBufferSize); if ((result > 0) && (pUnicodeBuffer != NULL)) pUnicodeBuffer[result-1] = 0; return result; } int Unicode2Ansi(const wchar_t* pUnicode, char* pAnsiBuffer, int nBufferSize) { if( (nBufferSize == 0) && (pAnsiBuffer != NULL) ) return 0; int result = ::WideCharToMultiByte(CP_ACP, 0, pUnicode, -1, pAnsiBuffer, nBufferSize, NULL, NULL); if ((result > 0) && (pAnsiBuffer != NULL)) pAnsiBuffer[result-1] = 0; return result; } int Ansi2Unicode(const char* pAnsi, wchar_t* pUnicodeBuffer, int nBufferSize) { if( (nBufferSize == 0) && (pUnicodeBuffer != NULL) ) return 0; int result = ::MultiByteToWideChar(CP_ACP, 0, pAnsi, -1, pUnicodeBuffer, nBufferSize); if ((result > 0) && (pUnicodeBuffer != NULL)) pUnicodeBuffer[result-1] = 0; return result; }

简单实用

CString strBuf; int nSize = Unicode2UTF8(strBuf, NULL, 0); char* szBuf = new char[nSize]; Unicode2UTF8(strBuf, szBuf, nSize);
