How it works

How it works

Iterates characters with for...of, which walks Unicode code points (not 16‑bit code units).
No normalization: visually identical forms (e.g., é vs e+◌́) count separately. Normalize first if needed (str.normalize('NFC')).
Whitespace visualization: spaces show as “(space)”, newlines as ↵, tabs as → to make them visible.
Percentages are per total characters; empty input is guarded to avoid divide‑by‑zero.
