Arabic WhatsApp chats as PDF, right to left and joined

Arabic letters take different shapes at the start, middle and end of a word, and most join to their neighbours. A renderer that ignores this prints isolated letters, which are hard to read. Add right-to-left order, and a tool built for English often produces text that is both disconnected and reversed.

Chats in Israel often move between Arabic, Hebrew and English in one message, with numbers, times and amounts in between. Each run has to keep its own direction while the message as a whole stays right to left. Nispach applies the Unicode bidirectional algorithm to every message, so a line like an address in Hebrew followed by a time in Arabic stays readable.

Many people write Arabic in Latin letters (Arabizi) or in Hebrew letters. These messages are kept exactly as typed, in the direction of the script they use.

The appendix label is free text, so it can be ملحق 1, נספח א' or Appendix A, depending on the language of the filing. The cover page lists participants, date range and the SHA-256 hash of the source export.
