> 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.
