+### Coming from Python

+If you know Python's `unicodedata`, the normalization entry points map directly:

+| Python                                  | mojo-unicodedata               |
+| --------------------------------------- | ------------------------------ |
+| `unicodedata.normalize("NFC", s)`       | `normalize("NFC", s)`          |
+| `unicodedata.normalize("NFKD", s)`      | `normalize("NFKD", s)`         |
+| `unicodedata.is_normalized("NFC", s)`   | `is_normalized("NFC", s)`      |
+| `s.casefold()`                          | `casefold(s)`                  |
+
+These are module-level functions. If you normalize many strings, construct a
+`Normalizer()` once and call `.normalize(form, s)` / `.casefold(s)` on it to
+reuse the loaded tables.
