There is 99% chance the software you are reading text on right now uses HarfBuzz to lay out the text, a library written mainly by a Persian person. https://en.

  I believe that’s the specific guy that was referenced.

    That is not the point I’m making, rather a single person is responsible for how most of software render text in most of the world writing systems and no one is wondering how 6 billion people on this planet so much depend on the work of “this one guy”. It is because text layout is something 99% of software developers can’t do right if their lives depended on it (same for anything that involves the irregularities of human nature, software developers are not cut for this).

Many can't even get the spaces before and after punctuation right, even though the correct way involves no irregularities.
