No, you aren't aware of the whole problem. String comparison with
invariant culture does not mean that it has no other side effect
than case insensitivity. With CultureInfo dependent (including
InvariantCulture) there are some characters that are ignored in the
comparison (and sometimes culture-sensitive comparison is buggy, at
least with MS.NET) or regarded equivalent to other character
sequences.

Try

	Console.WriteLine (String.Compare ("\u00C6", "AE",
		true, CultureInfo.InvariantCulture));

under MS.NET.
