Frequently asked questions
Why does 'finally' from a PDF come out as 'finally'?+
PDFs use typographic ligatures (fi) for fi and fl combinations. The stripper replaces those Unicode ligature characters with their standard ASCII equivalents.
What is a soft hyphen and why is it a problem?+
A soft hyphen (U+00AD) is an invisible hyphenation hint used in typeset documents. It breaks string matching and shows as a visible hyphen in some environments.
Does this fix column alignment issues from PDF extraction?+
No. Column alignment problems from PDF extraction (cells split across columns) need manual correction or a more advanced extraction tool.
