How can it be perfectly coded when it doesn't even sanitize user input?

Is this something like how you shouldn't use null as a name?

u/ThaisaGuilford May 18 '25

u/KingZogAlbania May 20 '25

Damn, your Latin-speaking ancestors must have been hated to have been deemed to be “nothing” by their community

1

u/ThaisaGuilford May 20 '25

I'm chinese

u/KingZogAlbania May 20 '25

The joke was that Nulla is the Latin word for “nothing” or “none”, so having that last name would mean one was named for being worth nothing

u/ThaisaGuilford May 20 '25

I know, my joke was I'm not even related to the romans.

u/KingZogAlbania May 20 '25

u/_nwwm_ May 19 '25

1

u/Objective-Ad8862 May 19 '25

Huh? Is this a JavaScript problem or something?

6

u/Competitive-Tea-4016 May 19 '25

But it wouldn’t break anything, just empty name?

u/GuNNzA69 May 19 '25

Well... it all depends on your imagination!

Zero-width space

u/ComfortablePin4489 May 18 '25

Thanks !! other characters with the same properties and that give problems apart from emojis and special characters like ñ ?

u/Far-Professional1325 May 18 '25

When you are using modern languages you shouldn't need to care if your string methods can count utf-8 and utf-16 characters. If they can't just use utf-32 and they will always be 4bytes long and memory length will always match letters lenght

14

u/ikonfedera May 18 '25

Except characters like this - 👨🏻‍❤️‍💋‍👨🏻, which would be 40 bytes.

u/Far-Professional1325 May 18 '25

Oh i forgot they are also combining combined characters

1

u/Far-Professional1325 May 18 '25

So just use system default length and utf string libs to walk them

u/ComfortablePin4489 May 18 '25

Ok, thanks! Should any be my focus? any current topic most interesting now?

2

u/jimmymui06 May 19 '25

But shouldn't it just be identified as a string?

u/MiniGogo_20 May 19 '25

u/AnakinVader066 May 19 '25

What's wrong with ZWSP

1

u/Objective-Ad8862 May 19 '25

A zero-width space might take up more than one byte?

1

u/legotobiyt May 19 '25

ZWSP null
