I think it’s more of an ethical question than anything. There will always be pranksters and there will never be perfect input validation for names. So who do you oppress? The people with uncommon names? Or the pranksters? I happen to think that if you do your job right, the pranksters aren’t really a problem. So why oppress those with less common names?

I am not saying to only allow [a-zA-Z ]+ in names, what I am Saying is that it is ok to block names like "'; drop table users;" or "<script src="https://bad.site.net/></script>" if part of your business is to distribute that data to other consumers.

And I’m arguing, rhetorically, what if your name produces a syntax error—or worse means something semantically devious—in the query language I’m using? Not all problems look like script tags and semicolons.

It's a question of intent. There aren't any hard and fast rules, but if someone has chosen their company name specifically in order to cause problems for other people using your service, then it's reasonable to make them change it.

This is getting really absurd. Are you also going to complain that Unicode is too restrictive or are you going to demand being able to use arbitrary bytes as names. Images? If Unicode is enough, then which version.

There is always a somewhat arbitrary restriction. It's not unreasonable to also take other people into account besides the user wanting to enter his special snowflake name.

No one is being oppressed. Having to use an ASCII version of your name is literally a non-issue unless you WANT to be offended.

Maybe also think of the other humans that will need to read and retype the name. Do you expect everyone to understand and be able to type all characters? That's not reasonable. The best person to normalize the name to something interoperable is the user himself, so make him do it at data entry.

I was saying the exact same thing about how I don't understand why people get offended when they have to transcribe their name to use Hanzi!

We should have a world vote to settle which alphabet we use.
