How Hexadecimal Encoding Works
Hexadecimal (base-16) uses digits 0-9 and letters A-F to represent data.
Each byte is converted to two hex characters for compact representation.
UTF-8 encoding ensures multi-byte characters are handled correctly.
Spaces and formatting in hex input are automatically removed during decoding.
