Why Does it generate different result ? using ASCIIEncoding.GetChars(..), ASCIIEncoding.GetString(..

[±èÀçȲ]

When you use the ASCIIEncoding class, its GetChars(..) method decode the
bytes as '?' if bytes[index] higher than 0x7f.
But its GetString(..) method decode the bytes using this code that is 0x7f &
bytes[index].
Why..?

ASCIIEncoding.GetString(..)
Why Doesn't it generate same result ?

Encoding e = Encoding.ASCII;

byte[] b = Encoding.Unicode.GetBytes("°¡");

foreach(char c in e.GetChars(b))
Console.Write(c);

Console.WriteLine();

Console.WriteLine(e.GetString(b));

It looks like GetChars is basically a bit more rigorous. I'd noticed
GetString being pretty lax before, but not that GetChars does the right
thing. Interesting...
