Interactive ASCII/Unicode to Binary/Decimal/Hex Decoder
An interactive, "ajax-style" mini-application, supporting conversion
to binary/decimal/hex as you type, copy/paste of ASCII and Unicode characters.
If you type/copy/paste non-ASCII characters like 您好 you will
see their unicode representation -- note that non-ASCII characters are
represented in more than 8 bits, so you may need to increase the pad amount
to fit the longest character.
