Hello, @zlm0001! I'm here to help you with any bugs, questions, or contributions you have for dify. Let me know how I can assist you!

I found a similar closed issue regarding PDF files resulting in garbled text due to font or layout issues. The suggested solution was to use another tool to export the PDF as a plain text (txt) or markdown (md) file before importing it into Dify. Additionally, there was a mention that integrating OCR in the future might help improve this issue [1].

To continue talking to Dosu, mention @dosu.
