General PDF tools print Arabic, Urdu and Persian with disconnected letters, reversed words or empty boxes. RTL PDF lays the text out with a full typesetting engine (letter shaping and the Unicode bidirectional algorithm) and bundled SIL Open Font License fonts (Noto Naskh Arabic, Noto Nastaliq Urdu, Cairo, Tajawal), and returns a download link valid for 24 hours. make_pdf_arabic supports headings, paragraphs, bullet and numbered lists, tables and bold text written as light Markdown; A4, A5 and Letter; Arabic and English in one line with numbers, dates and phone numbers kept in order; optional 3 mm bleed with crop marks; and optional PDF/A with PDF/UA export. check_arabic_text finds pre-shaped or reversed letters copied out of broken PDFs, Persian or Urdu letters mixed with Arabic ones, hidden direction marks and characters the fonts cannot print, and suggests a fixed text. No AI is used inside the tools: they do not write, translate or change wording. Text is not stored; the finished PDF is kept for 24 hours so the link works, then deleted.
