Could you clarify why you think this should work? As far as I can tell \p has no special meaning in regex.

[ronaldoussoren]

They may mean character properties as described here: https://www.unicode.org/reports/tr18/#property_syntax

Perl has similar functionality.

Unicode properties are supported in the 'regex' package on PyPI here: https://pypi.org/project/regex/

re: 應該支援漢字正則表達式 \p{Han}

Please write the issue title in English if possible, some of the core devs are not familiar with Chinese.
(Same reason why I do not write issue titles in Korean.)
For reducing the cost of understanding your suggestion, I re-wrote the issue title in English.

Removing the pending label because @ronaldoussoren explained what the OP means.

Note: currently re supports only \number, \a, \b, \f, \n, \N, \r, \t, \u, \U, \v, \x, and \\.
