Description

Is your feature request related to a problem? Please describe.

Not so long ago there was an issue where it was told about RegularExpressionAttribute problems. This eventually led to a clarification in the documentation.

(By the way, it ended up in the wrong section. Therefore, in the documentation, we see it only for a version below aspnetcore-3.0)

But, ECMAScript 2015 does support language elements such as the Unicode category or block elements \p and \P. Now we have to write workarounds. See this SO-answer.

(If I understand correctly, this is now supported by all browsers in this table, except Konq 4.14 and IE 11)

Contributor guide

Research direction
Investigate how to integrate Unicode aware regex features (\p{...}, \P{...}) into the RegularExpressionAttribute without breaking existing behavior. Review the current implementation and ECMAScript 2015 compatibility tables.
