Hi, is it possible to sanitize custom identity schema strings like removing links in the name?

You can use regex in the identity schema to disallow some patterns.
For example
```"username": {
  "type": "string",
  "minLength": 6,
  "maxLength": 32,
  "pattern": "^[a-zA-Z0-9]*$",
  "title": "Username",
  }```
If you use this method we recommend to customize the error on the client side, see <https://www.ory.sh/docs/kratos/concepts/ui-user-interface#titles-labels--validation-messages>

You can also use webhooks for more advanced validation.
