Display UNICODE characters in Listview

I have a form in MS Access with a listview control.
Some values I need to display are in unicode, but the listview will not show the characters, just replaces them with question marks.

I've looked at other articles such as:
http://www.experts-exchange.com/Programming/Languages/Visual_Basic/Q_20252634.html?sfQueryTermInfo=1+10+30+listview+unicod
and tried using SendMessage as in attached code (I call the SendMessage function in form's module at time of populating Listview.)
The function returns 1 - suggesting the listview did receive the message, but still the characters are in ANSI, not unicode.
Listview class is MSComctlLib.ListViewCtrl.2 and Access is running on MS Office 2003/Windows Server 2003.

Any suggestions?
Public Declare Function SendMessage Lib "User32" _
         Alias "SendMessageA" _
         (ByVal hWnd As Long, _
         ByVal wMsg As Long, _
         ByVal wParam As Long, _
         lParam As Long) As Long

Public Const CCM_FIRST = &H2000&
Public Const CCM_SETUNICODEFORMAT = (CCM_FIRST + 5)
Public Const LVM_SETUNICODEFORMAT = CCM_SETUNICODEFORMAT
Public Const CCM_GETUNICODEFORMAT = (CCM_FIRST + 6)
Public Const LVM_GETUNICODEFORMAT = CCM_GETUNICODEFORMAT

Call SendMessage(ListView1.hWnd, LVM_SETUNICODEFORMAT, 1, ByVal CLng(0))

Hi
I've seen that article. It doesn't help. I can display the unicode string in a text box, but the listview activex control will not display unicode.
It's used to list file names; when user double-clicks, then it will launch that file. Once the listview receives the unicode string, it converts it to plain ANSI.

Hi
yes, I also saw that. It tends to contradict documentation on Microsoft's technet site; if it cannot display unicode, why would they document the LVM_SETUNICODEFORMAT parameter in the first place?
Even if it were true that I'm at a dead end with Microsoft's control, I'm a bit reluctant to roll out other ActiveX controls. The Access db is used on several different platforms (including 32 and 64 bit) and using non-standard controls can add another layer of administration - not withstanding any licensing issues as this is a business application.
thanks

following worked for me, as advised by Chinese colleague:

regional and langage setting => set the Language for non-Unicode programs to 'Chinese (PRC)'
