True, I forgot those final forms in Hebrew. Perhaps my mind is conflating them with the initial capital letters of sentences and names in most text with Latin letters. On the different forms, https://en.wikipedia.org/wiki/Arabic_script_in_Unicode https://en.wikipedia.org/wiki/Arabic_script_in_Unicode has a short summary. It is possible to type those contextual forms explicitly (they have their own code points), but "presentation forms are present only for compatibility with older standards, and are not currently needed for coding text."
