Takes Arabic text as an input and performs Arabic glyph joining on it and outputs a UTF-8 hexadecimals stream that is no longer logically arranged but in a visual order which gives readable results when formatted with a simple Unicode rendering just like GD and PDF libraries that does not handle basic connecting glyphs of Arabic language yet but simply outputs all stand alone glyphs in left-to-right order.
What is happening?
Computers are designed to handle the subset of the Latin script required to manipulate American English first
and foremost. Every other writing system is an afterthought, and Arabic is particularly poorly served. Most of
the images in Nope, Not Arabic archive are the result
of non-Arab graphic designers pasting Arabic text into mainstream graphic design software that cannot handle
anything but Latin characters and not checking with a native speaker.
