Load a Unicode file into a TMemo

Answer:
1   
2   procedure LoadUnicodeFile(const filename: string; strings: TStrings);
3   
4     procedure SwapWideChars(p: PWideChar);
5     begin
6       while p^ <> #0000 do
7       begin
8         p^ := WideChar(Swap(Word(p^)));
9         Inc(p);
10      end;
11    end;
12  
13  var
14    ms: TMemoryStream;
15    wc: WideChar;
16    pWc: PWideChar;
17  begin
18    ms := TMemoryStream.Create;
19    try
20      ms.LoadFromFile(filename);
21      ms.Seek(0, soFromend);
22      wc := #0000;
23      ms.write(wc, sizeof(wc));
24      pWC := ms.Memory;
25      if pWc^ = #$FEFF then {normal byte order mark}
26        Inc(pWc)
27      else if pWc^ = #$FFFE then
28      begin {byte order is big-endian}
29        SwapWideChars(pWc);
30        Inc(pWc);
31      end
32      else
33        ; {no byte order mark}
34      strings.Text := WideChartoString(pWc);
35    finally
36      ms.free;
37    end;
38  end;
