Frequently asked
Why is emoji so long in binary?
Emoji live in the astral planes of Unicode and typically encode to 4 bytes (32 bits) in UTF-8. Even simple Latin letters are 1 byte (8 bits).
What encoding does the tool use?
UTF-8 — the modern standard. That means ASCII characters (a-z, digits) are 1 byte; most Latin-extended and European chars are 2 bytes; CJK and emoji up to 4.
