This project is not covered by Drupal’s security advisory policy.

Search engines like Solr can choke on invalid data in your fields. That could be the result of a migration, programmatically created nodes or something else. The purpose of this module is to provide a processor that prevents non-UTF-8 data to be sent to the search engine.

Our original blocker was this error message: "Invalid UTF-8 character 0xfffe at char" from Solr 6.x, but the module could be useful in different scenarios as well.

Share your own case in the issues to make the sanitization even more robust.
