import { MongoClient } from 'mongodb'

const client = await MongoClient.connect(process.env.CLUSTER);
const db = client.db("test");
const coll = db.collection("invalidutf8");
for await (const doc of coll.find({}, { enableUtf8Validation: false }));
await client.close();

works on 6.7.0, broken on 6.8.0. Data inserted using inserted.py from https://gist.github.com/addaleax/a892522a21ca87d206d991a0b97b4c6c.

Use Case

As a... driver user
I want... to be able to read documents that contain invalid UTF-8
So that... I can recover from that invalid data

User Experience

enableUtf8Validation should work like it did in previous verisons. This is particularly relevant considering the impact of NODE-6349.

Risks/Unknowns

• What could go wrong while implementing this change? (e.g., performance, inadvertent behavioral changes in adjacent functionality, existing tech debt, etc)
• Is there an opportunity for better cross-driver alignment or testing in this area?
• Is there an opportunity to improve existing documentation on this subject?

Acceptance Criteria

Implementation Requirements

• functional reqs, potential snafus to avoid, performance targets, etc

Testing Requirements

• unit test, spec test sync, etc

Documentation Requirements

• DOCSP ticket, API docs, etc

Follow Up Requirements

• additional tickets to file, required releases, etc
• if node behavior differs/will differ from other drivers, confirm with dbx devs what standard to aim for and what plan, if any, exists to reconcile the diverging behavior moving forward
