The regular expression \p{P} is a Unicode property that matches any
punctuation character. This includes a wide range of symbols used in writing
to separate sentences and words, indicate pauses, or convey other structural
or expressive functions. Here is a list of some common punctuation characters
that \p{P} would match:

Period: .
Comma: ,
Question mark: ?
Exclamation mark: !
Colon: :
Semicolon: ;
Quotation marks: " and '
Apostrophe: '
Hyphen: -
Dash: b (em dash) and b (en dash)
Parentheses: ( and )
Brackets: [ and ]
Braces: { and }
Slash: / and \
Vertical bar: |
Ellipsis: b&
Angle brackets: < and >

This list is not exhaustive, as Unicode includes many other punctuation marks
used in various languages and scripts. The \p{P} property covers all such
characters, including those specific to certain languages or typographic
conventions.

The exact number of characters matched by \p{P} can vary depending on the
version of the Unicode standard being used, as new punctuation characters may
be added in future updates. As of Unicode 15.0, which was released in
September 2022, there are over 100 punctuation characters. This includes
common punctuation marks like periods, commas, and quotation marks, as well as
less common ones used in various languages and scripts.

For the most precise and up-to-date count, you would need to refer to the
Unicode Character Database for the specific version you are interested in. The
database provides detailed information about each character, including its
properties and classifications.
