Description
Activity
Could you clarify why you think this should work? As far as I can tell
\phas no special meaning in regex.Reacted by 朧月They may mean character properties as described here: https://www.unicode.org/reports/tr18/#property_syntax
Perl has similar functionality.
Reacted by 朧月 and Oleg IaryginUnicode properties are supported in the 'regex' package on PyPI here: https://pypi.org/project/regex/

For reducing the cost of understanding your suggestion, I re-wrote the issue title in English.Reacted by 朧月 and Daniël van NoordRemoving the

[-]re: should support Chinese character regular expression \p{Han}[/-][+]`re` should support `\p{...}` character properties[/+]on Mar 4, 2023 Note: currently re supports only
\number,\a,\b,\f,\n,\N,\r,\t,\u,\U,\v,\x, and\\.As a concrete example where this limitation can cause problems: while JSON Schema formally only supports a limited number of escape sequences, in practice schemas may end up containing patterns that use any of the defined JavaScript regex character classes.
Python supports most of the same character classes, but
\p/\Pis a notable omission. Whether or not that can reasonably be worked around by usingregexinstead ofredepends on how the affected regex is being processed (if it's in a third party library, it may not be straightforward to get it to use a different regex engine)- added 4 commits that reference this issue
