String.prototype.normalize() β€” NFD

NFD (Canonical Decomposition): decomposes precomposed characters into base + combining marks.

'\u00e9'.normalize('NFD') β†’ '\u0065\u0301' (2 code units).

Challenge: Implement toNFD(str) using .normalize('NFD').

πŸ’‘ Hints (1)
  • β€’ NFD splits precomposed characters into their base character + combining diacritic marks.
