Frequently asked questions

How is sorting done for Arabic?

Sorting uses Intl.Collator for the page language, which follows the alphabetical order of that language rather than raw character codes.

Which line endings are supported?

Windows (CRLF), Unix (LF) and old Mac (CR) line endings are all recognised. Output uses LF.
