Text is converted to UTF-8 bytes and each byte is represented by eight binary digits.
Example:
01001000 01101001 instead of 0100100001101001
HOW IT WORKS
Binary represents the underlying UTF-8 bytes
Each byte is displayed as eight binary digits. ASCII characters normally use one byte, while many international characters and emoji require multiple UTF-8 bytes.
SECURITY NOTE
Binary encoding does not protect data
Binary is only another representation of the original data. It provides no encryption, authentication, confidentiality, or password protection.
