There are different ways to use UNICODE in ANSI build.

First, you know that UNICODE data is declared as WCHAR in Windows programs.
You can use wchar_t now, though. If you want to pass UNICODE string to a
function, but have TCHAR or CString source, you can use T2W macro (see "ATL
and MFC String Conversion Macros" topic). With VC7, you can use CStringW:

void f(LPCTSTR s)
{
FunctionW(CStringW(s));
}

This will create a temporary UNICODE CString, applying conversion, if
necessary. CT2W macro does about the same (but skips a temporary for UNICODE
build).

You don't quite understand what "scalable" means. LPCTSTR type definitely
doesn't break when the program workload gets greater or the program gets
larger.
