Dify version

0.15.2

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

  1. Click Create knowledge in Knowledge tab.
  2. Choose Import from file.
  3. Upload a text file with multiple lines with "Some text."="Some text." pattern.
  4. Click Next.
  5. Use general Chunk settings and '\n' as a delimeter
  6. Click Preview Chunk button

✔️ Expected Behavior

I expect to have chunks with a line in each chunk with the same "Some text."="Some text." pattern with all quotation marks.

❌ Actual Behavior

I get a line in each chunk without first quotation mark Some text."="Some text."

Hello @M4g3dd0! I'm here to help you with any bugs, questions, or contributions you have for the project. Let's work together to solve this issue.

The issue you're experiencing with the first quotation mark disappearing during the import process in Dify version 0.15.2 might be related to how the platform handles special characters during text processing. Unfortunately, I couldn't find specific information on known issues with handling special characters like quotation marks in the Dify import process.

However, you might want to check the chunking settings and ensure that the delimiters or any preprocessing steps aren't inadvertently altering the text. If the problem persists, consider reviewing the code responsible for text extraction and processing, particularly in the DocumentExtractorNode class, as it handles the extraction process [1].

If this doesn't resolve the issue, it might be beneficial to look into any recent changes or updates in the codebase that could affect text import and chunking, although no specific version-related changes were found for version 0.15.2 [1].

To continue talking to Dosu, mention @dosu.

Issue still exists in version 1.1.2.
The first quotation mark (" or ' or `) in each chunk is deleted when importing text into the knowledge base.
