Encoding (in the System.Text namespace) is an abstract class which is the parent of various specific encoding classes including ASCIIEncoding and UnicodeEncoding. ASCIIEncoding is a single byte encoding. Only the first 7 bits are used so the possible range is characters with ASCII values of between 0 to 127. Unicode uses two bytes to encode each character and is the native type used in .NET for the Char and String types. This gives it a range of 0 to 65535. There's also something called 'surrogate pairs' which extends the range still further. However they are unimportant and so I won't bore you with them just now :)
