``\d``
For Unicode (str) patterns:
- Matches any Unicode digit (which includes ``[0-9]``, and also many
- other digit characters). If the :const:`ASCII` flag is used only
- ``[0-9]`` is matched (but the flag affects the entire regular
- expression, so in such cases using an explicit ``[0-9]`` may be a
- better choice).
+ Matches any Unicode decimal digit (that is, any character in
+ Unicode character category [Nd]). This includes ``[0-9]``, and
+ also many other digit characters. If the :const:`ASCII` flag is
+ used only ``[0-9]`` is matched (but the flag affects the entire
+ regular expression, so in such cases using an explicit ``[0-9]``
+ may be a better choice).
For 8-bit (bytes) patterns:
Matches any decimal digit; this is equivalent to ``[0-9]``.
