Make long text feel like a book

Fix encoding, tidy spacing, organize chapters and inspect the EPUB.

Convert text encoding

Check for garbled characters before confirming the encoding. Repeated conversion cannot recover lost text.

Clean whitespace selectively, preserving meaningful paragraphs and headings.

Set the title, author and chapter rules, then review the generated table of contents.

Check the text and chapter navigation. Fonts and pagination can differ between readers.
