IMultiLanguage::GetCodePageInfo issue

[=?Utf-8?B?YXNycmpz?=]

I have an unmanaged VS2005 VC++ application using the MultiLanguage DLL
IMultiLanguage: :GetCodePageInf o method for obtaining MIMECPINFO information
for a given codepage.

I find that the valid codepage of 20127 fails. See the code below.

#include "mlang.h"
..
..
..
::CoInitialize( 0);
HRESULT hr ;
CComPtr<IMultiL anguagep;
hr = p.CoCreateInsta nce(__uuidof(CM ultiLanguage));
MIMECPINFO info;
hr = p->GetCodePageInf o(20127, &info);
// hr will be E_FAIL and the info struct will not be populated.

Any ideas on why this is failing? And how to correct this?
Thanks.
