UE4中FString转UTF8及UTF8转FString

FString转UTF8

 FString szMsg = "test msg";
 TCHAR* pSendData = szMsg.GetCharArray().GetData();
 int32 nDataLen = FCString::Strlen(pSendData);
 uint8* dst = (uint8*)TCHAR_TO_UTF8(pSendData);

UTF8转FString

 　TArray<uint8> receiveBuff;
 　RecvData(receiveBuff, buffLen));
    receiveBuff.Add('\0');
    FString str = FString(reinterpret_cast<const char*>(receiveBuff.GetData()));
