Normalization Forms

Unicode defines four normalization forms that affect how characters with diacritics, compatibility variants, and combining marks are represented. This character has a non-trivial normalization — the forms below differ from its codepoint. Mismatched normalization is the most common cause of failed string comparisons across systems.

NFC = Canonical Decomposition then Canonical Composition (preferred for storage) · NFD = Canonical Decomposition · NFKC/NFKD = Compatibility forms (fold variants like fi → fi)

Decomposition

This character can be broken down into a sequence of simpler Unicode codepoints. This is a compatibility decomposition — the character is a stylistic or semantic variant of its components, not an exact equivalent.
