Python 3.8+unicodedatafunction

unicodedata.is_normalized()

normalization

Checks whether a string is already in the given normal form, faster than calling normalize() and comparing.

Syntax

unicodedata.is_normalized(form, unistr, /)

Often the answer comes without building a new string, which is why it is called before normalize() on large texts. The form is mandatory: a two-code-point 'й' is False for 'NFC' but True for 'NFD', so 'normalized' means nothing without a form. It never changes the string; it was added in 3.8.

Examples

import unicodedata
s = 'и\u0306'  # й из двух кодовых точек
print(unicodedata.is_normalized('NFC', s), unicodedata.is_normalized('NFD', s))  # → False True
if not unicodedata.is_normalized('NFC', s):
    s = unicodedata.normalize('NFC', s)
print(len(s))  # → 1

unicodedata.is_normalized()
