Steps to reproduce

The current version of the document extractor cannot discard watermark level characters when processing PDF files with watermarks, and defaults to adding watermark characters to the document, resulting in incorrect recognition of document content.

✔️ Expected Behavior

Adding an optional document watermark symbol discard function to the document extractor.
Watermark symbols can be customized to input relevant characters for more accurate identification of watermark objects.

❌ Actual Behavior

Adding watermark characters to the document, resulting in incorrect recognition of document content.

For feature request, please use feature request template, also I would like to know whether the behavior "remove watermark" is against the data privacy law?
