Sample text file: UTF-8 with BOM, CRLF line endings
Free sample from 99helpers.com/file-types/txt

This file starts with a byte order mark (BOM), the three bytes EF BB BF.
Every line ends with a carriage return and a line feed (bytes 0D 0A).
That is the style Windows tools have often used.

What to check:
- An editor should not show the BOM as a character. If the first line
  starts with "", the program read the BOM as Windows-1252 text.
- A Unix tool such as cat -A shows each line ending as ^M$.
- Accented text should read correctly: Café, Zürich, Ærøskøbing, São Paulo.
- Symbols: € £ ¥ © ® ™ ° ± × ÷ ½

Last line, followed by CRLF.
