From the Urbit whitepaper:<p>&quot;Besides cosmetic details like character sets, this exercise should yield the same results on Mars as Earth.&quot;<p>My personal opinion is that if you believe that you need to re-invent everything (and that part might be true), you have a hard enough problem that time spent on &quot;Martian&quot; details (like the equals sign) both detracts from more important problems and alienates potential outside help.
