Range of printable Keycodes

Hey.. is there are range of "printable" key codes? ie.. if (Key > 47 And Key < 112) = a key that will produce a character in a text area.

I would work it out my self but i am lazy and the document for key codes is all crazy and out of order.

Example:

Alt key (Right) KEY_RALT 165
Tilde KEY_TILDE 192
Minus KEY_MINUS 107
Equals KEY_EQUALS 109
Bracket (Open) KEY_OPENBRACKET 219
Bracket (Close) KEY_CLOSEBRACKET 221

This is actually present in the OS (and in the users language too), so it *MIGHT* not be too hard to do BRL ;)
