Here are all the characters, you get them by holding the Alt key down while
entering the set of numbers on the numeric keypad. (That's the square block
of numbers on the right). The first character is just the number, the second
character has a leading zero and the number.
e.g. -- Alt+131= == Alt+0131=

What are they good for?
Here's a few letters with umlauts, needed for foreign languages :
129 = == 132 = == 137 = == 148 = == 142 = == 153 = == 154 =
A few of my favorites are :
Alt + 0162 = == Alt + 0169 = == Alt + 0174 =
Alt + 0153 = == Alt + 0222 = == Alt + 0191 =
