NFC composes a letter and its accent into one code point, while NFD splits them apart so the base letter and the mark are separate.
Use NFKC when you want aggressive tidying, such as turning full width characters or ligatures into their plain equivalents for search.
It removes the accents and diacritics that sit on top of letters, so an e with an acute accent becomes a plain e.
Decomposition forms add extra characters for the accent marks, while composition and stripping remove them, so the length can change.
Yes. Normalisation applies to every script the browser knows, and emoji sequences are left as they are by normalisation.
No. The browser performs the normalisation locally and your text never leaves your device.
