[Lazarus] Windows CE

[Lazarus] DLL unicode value
Hi,
I want to get unicode value from an mp3 file and I used MediaInfo
library for this and its unicode support and I used unicode methods.
Code is simple :
MediaInfoDLL_Load('MediaInfo.dll'); HND := MediaInfo_New();
MediaInfo_Open(HND, 'test.mp3'); ListBox.Items.Add(MediaInfo_Get(HND,
Stream_General, 0, 'Title', Info_Text, Info_Name)); //MediaInfo_Get:
function (Handle: Cardinal; StreamKind: TMIStreamKind; StreamNumber:
Integer; Parameter: PWideChar; KindOfInfo: TMIInfo; KindOfSearch:
TMIInfo): PWideChar cdecl stdcall;
It work if Title value is ansi but if it is unicode it returns
??? ! But if I debug andset value to an string it's deug it shows
me correct value.
s:=MediaInfo_Get(HND, Stream_General, 0, 'Title', Info_Text,
Info_Name);//in debug s hint shows correct value but ListBox add ???
ListBox.Items.Add(s);
