How can I get Visual Studio 2010 to show Chinese comments properly

I have some code from a Chinese business partner, and all of the comments in the code are in Chinese. However, Visual Studio displays them as gibberish. How can I get them to display properly. Here is a code example with some comments converted to gibberish:

//Á¬½Óµ½·þÎñÆ÷
void CTestAPIDlg::OnBnClickedButton2()
{
    UpdateData(TRUE);
    //ÉèÖÃÊÇ·ñ¼ÇÂ¼ÈÕÖ¾
    m_ObjRSI->EnableLog(m_bIsOnLogReg,m_bIsOnLogComm);
    //ÅÐ¶ÏÊÇ·ñÆôÓÃ´úÀí
    if (m_bIsOnProxy)
    {
        //´úÀí²ÎÊý
        char proxyIP[64];
        ZeroMemory(proxyUserPwd,sizeof(proxyUserPwd));
        //×¢£º´Ë´¦ÒòÎªÊÇÊ¹ÓÃunicode±àÒë£¬ËùÒÔÒª×Ö·û×ª»»£¬ÏÂÍ¬.
        WideCharToMultiByte(CP_ACP,0,m_strProxyIP,-1,proxyIP,64,NULL,NULL);

etc...

Thanks in advance for any help...

Solution

Ask your partner to save the source code file encoded in UTF-16 or UTF-8. It is still not the default encoding for C++ source code, Unicode is slow to catch up. File + Save As, click on the arrow of the Save button, Save with Encoding, choose UTF-8.

You should be able to do this yourself as well. File + Open, select the .cpp file(s), click on the arrow of the Open button, Open With, select "C++ Source Code Editor (with encoding)". Pick the correct Chinese encoding (there are several to choose from) from the Encoding dialog box.
