Here's a better analogy, in the 70s "nobody planned" for names with 's in then. SQL injections, separators, "not in the alphabet", whatever. In the US. Where a lot of people with 's in their names live... Or double-barrelled names.

It's a much simpler problem and still tripped a lot of people

And then you have to support a user with a "funny name" or a business with "weird characters", or you expand your startup to Canada/Mexico and lo and behold...
