Cool article, but the one it acknowledges and riffs off of, at https://lr0.org/blog/p/arabic/ , is much more informative, and tells all about how we got decent Arabic script rendering on our browers and OSs, but still notably imperfect.
Which makes me think: come on, in the age of Claude, the gap between "we know what to do" and "here is the working code" is narrower than ever.
Who will be the one to pick up the job? Has to be an Arabic speaker I guess!
