"We call her Carrie, because of the carriage return."

You can also try to give the child NULL as middle name for additional fun.

I have an apostrophe and it's super annoying as some companies see it as a SQL injection hack and sanitize it.

So I've received ID with Mc%20dole or they add a space in it. Or I'll get a work email with an apostrophe but I cant use it anywhere because sites have it disabled. And I've missed my flight because I changed my ticket once to add the apostrophe and the system just broke at the gate.

Worse yet many flight companies have "you will not be able to board if your ID doesn't exactly reflect your details" but their form doesn't allow it. Even most forms for card payments don't allow it even though it's the name on my card.

asking questions like this is how i found out that one of the allowed characters in names in my country is ÿ, which is fine in Latin-1 but in 7-bit ASCII is DEL.

That's easy, just call it Jhon\nDoe

There are a frightening number of systems that don't allow "-", which isn't even an edge case. A lot of people - mostly women - hyphenate their last names on marriage, rather than throw their old name away. My wife did. She legally changed her name when she came of age, and when we met and married years later she said, "I paid for money for my name; I'm not letting it go." (Note: I wasn't pressuring her to take my name.) So she hyphenated it, and has come to regret the decision. She says she should have switched, or not, but the hyphen causes problems everywhere. It's not a legal character in a lot of systems, including some government systems.

Once I was tasked with doing QA testing for an app which was planned to initially go live in the states of Georgia and Tenessee. One of the required fields was the user's legal name. I therefore looked up the laws on baby names in those two states.

Georgia has simple rules where a child's forename must be a sequence of the 26 regular Latin letters.

Tenessee seemed to only require that a child's name was writable under some writing system, which would imply any unicode code point is permissible.

At the time, I logged a bug that a hypothetical user born in Tenessee with a name consisting of a single emoji couldn't enter their legal name. I reckon it would also be legal to call a Tenessee baby 'John '.

Not legal in Canada. Your legal name must use Latin characters only. This is a sore point for indigenous people.

What's the answer? I need the link

Edit: I found it

No, cause "John\nDoe" messes up my regex. Sorry, out of the question. I'm not good with regex.

Just noticed that the listing for ; DROP TABLE "COMPANIES"; -- LTD has been redacted by the government website‽

Can I kill someone who wants to do this? How do I legally get away with it?

If elected president my first order of business will be to make all birth certificates fully unicode compatible.

Not legal in Sweden. Our "IRS" must also accept the name and deem it legal.

I for one like this. As it stops some very stupid people to name their children some very stupid names. Such as "Adolf Hitler".

And yes. Someone did try to name their child this and they were appropriately stoped from doing it.

I'd rather include a bell character '\a'

C programmers would ask whether a null-terminated name would be acceptable

Ask Robert'); DROP TABLE Students; 's mum how it went.

Frontend devs hates this guy.

I want the char 8 that makes a beep.

Easy, John\nDoe

NaN,
Not a Number, and now Not a Name

It's impossible to represent that on paper. It could be misrepresented as a specific number of spaces. Depending on the position on the paper, it may also be hard to tell if the carriage return comes with the line feed. Unless you want the document to be in ASCII or EBCDIC hex, it's like writing an ambiguous math problem where the answer is different depending on how you were taught about the order of operations. Don't do this to your kid, Abcde.

Na, names are about pronunciation (how you call someone). Written letters are an approximation of that. You can't pronounce a newline, so there's that.
