Interesting note about that, because Arabic presents that same transliteration issue, a lot of U.S. units working in Middle Eastern countries had to pass out a standardized "you will spell names like this" guidance.

Because there was nothing keeping Soldier 1 from spelling a name Mohommad, and Soldier 2 from spelling it Muhammad, and then when the guy showed up on a base to look for a job, or clear security, whatever, Soldier 2 wouldn't be able to find "Muhammad" in the computer system, and the databases would be all messed up.
