String to Unicode?

Hi.
I am trying to convert a string/pchar to unicode. The problem is when I call MultiByteToWideString I get a "privilege" error. I am wondering why I can not call this function when it is possible to call them from C++ Compiler. Is there another way to convert to unicode? (UTF8ToUnicode function gives same error)

Thanks!

if you have an UTF8 string then use UTF8Decode()
for ansi strings you can use StringToOleStr()

function Utf8ToUnicode(Dest: PWideChar; Source: PChar; MaxChars: Integer): Integer;
var
count: Integer;
c: Byte;
wc: Integer;
begin
if Source = nil then
begin
Result := 0;
Exit;
end;
Result := -1;
count := 0;
if Dest <> nil then
begin
while (Source^ <> #0) and (count < MaxChars) do
begin
wc := Integer(Source^);
Inc(Source);
if (wc and $80) <> 0 then
begin
wc := wc and $3F;
if (wc and $20) <> 0 then
begin
c := Byte(Source^);
Inc(Source);
if (c and $C0) <> $80 then Exit; // malformed trail byte or out of range char
wc := (wc shl 6) or (c and $3F);
end;
c := Byte(Source^);
Inc(Source);
if (c and $C0) <> $80 then Exit; // malformed trail byte

Dest[count] := WideChar((wc shl 6) or (c and $3F));
end
else
Dest[count] := WideChar(wc);
Inc(count);
end;
Dest[count] := #0;
end
else
begin
while Source^ <> #0 do
begin
c := Byte(Source^);
Inc(Source);
if (c and $80) <> 0 then
begin
if (c and $F0) = $F0 then Exit; // too many bytes for UCS2
if (c and $40) = 0 then Exit; // malformed lead byte

if (Byte(Source^) and $C0) <> $80 then Exit; // malformed trail byte
Inc(Source);
if ((c and $20) <> 0) and ((Byte(Source^) and $C0) <> $80) then Exit; // malformed trail byte
Inc(Source);
end;
Inc(count);
end;
end;
Result := count;
end;
