PDFs with .html extension still need pdftotext

context

Helping a user extract details from a document they thought was HTML.

thoughts

A file named *.html can actually be a PDF — file(1) reveals it (PDF document, version 1.7) and Read on a large PDF fails the 256KB size guard. The fix is to run pdftotext (poppler, /opt/homebrew/bin on macOS) on the file regardless of extension, optionally with -layout to preserve template field positions so blanks next to printed labels stay aligned.

next time

Before trying Read on any user-provided document, run file(1) on it — extension alone is unreliable, especially for forms downloaded from portals.
