Regular expressions in pattern fields are not evaluated correctly

[febus982]

Description

Unicode characters supported by the /u regex flag are not parsed correctly (i.e. \u{6FFFE})

Additional context: I am implementing a solution that uses CloudEvents message format. The CloudEvent spec defines a specific set of allowed characters. One of the rules is excluding unicode non-characters.

I am using Faststream + Pydantic models, this means the Rust regex implementation is used to evaluate the regex (which doesn't support backtracking). The only way to have a validation regex which is both compatible with Rust and the ECMA format is to specify such characters with this format \u{6FFFE}.

The attached file is a valid spec, except for the fact that the validation of the examples fails due to such characters not being validated.

Expected result

Regex containing unicode characters to be evaluated correctly (or a way to disable validation on examples perhaps?)

Actual result

Validation stops the rendering

Steps to reproduce

Render this file (i.e. in https://studio.asyncapi.com/) asyncapi.json
