UTF-8 encoder/decoder

Encode UTF-8 characters into binary, hexadecimal, or decimal numbers with an optional signed byte offset. You can also decode an encoded message into UTF-8 characters, with an optional signed byte offset.

Big offset numbers when encoding or decoding to HEX or BIN can lead to overflow. Remember that if you encode with a positive offset (e.g +8), you have to decode with a negative offset (-8) to get back to the original message.
