Automated PDF Text Extractor

I have a PDF in which only specific pages matter to me—the ones that hold a concise list of content. I need a small script that will: pull out every character from those pages, keep the list order exactly as it appears, and drop the result into a clean UTF-8 .txt file. No images, tables, or other elements are involved, just text.

A lightweight Python solution is fine (PyPDF2, pdfplumber, PDFMiner, or similar), as long as it runs on Windows and macOS without extra paid dependencies.

Please deliver:
• The fully commented script
• A short README that shows the command-line call and any required libraries
• One sample output file produced from my PDF, proving list integrity is preserved

The job is complete when I can run the script, point it to the PDF, and get back an identical plain-text list every time.
