## Conversation Summary

assistant: MinerU finished processing. Here's the account number it extracted:

```
Account number: 777708Xd
```

**Same result as PyMuPDF** — both tools struggle with this particular PDF. The issue is likely that the account number is embedded in an image region with non-standard encoding, causing OCR to misinterpret the characters.

**For this M1 statement PDF specifically:**
- PyMuPDF: `777708Xd` (garbled)
- MinerU: `777708Xd` (same garbled result)

Neither would have given you `0857` without human verification. The PDF has non-standard text encoding that confuses OCR.

**Bottom line:** For financial PDFs with complex layouts, human review of extracted account numbers is still necessary regardless of the tool.
