    Description

      When a PDF has special characters ("", "=",">", "-"), when the text is extracted from the document, these characters show up with different symbols.

      I've attached two PDFs that illustrate the issue differently:

      • 625006.pdf has multiple pages. When the text is extracted from a table, certain characters show up as a ? symbol.
      • example.pdf is a single page with the same table. When the text is extracted the same characters show up as " or # symbols.
