What if chapter detection misses?

Switch to Custom regex and write your own; it is matched line by line and a matching line becomes the chapter title. To split on a row of asterisks, for example, use ^\*+$. You can also pick One chapter per file and split the text yourself.

Can a sentence mentioning a chapter be mistaken for a heading?

Almost never. A heading line has to be short and the number must be followed by whitespace, punctuation or the end of the line, so a sentence that continues past the number is left alone.

Will it work on a Kindle?

Yes. Recent Kindle firmware reads EPUB directly, so Send to Kindle is enough; for very old models convert to AZW3 with Calibre.

How is the encoding repaired?

By scoring bytes: valid UTF-8 is used as-is, otherwise GBK, Big5, Shift_JIS and EUC-KR are scored on how plausible the resulting characters look. If the preview still looks wrong, set the encoding by hand.

Do Markdown files work?

Yes. Choose Markdown headings and the first two heading levels become chapters; deeper hashes are stripped and the text stays as a paragraph.

📗TXT to EPUB - Turn a Text File into an Ebook with Chapters

A book saved off the web is usually one multi-megabyte text file: no table of contents, no way to find your place, and often an encoding that shows up as garbage. This tool turns it into a proper EPUB — chapter lines become a real table of contents, the encoding is repaired, and title, author and cover are filled in.
