But that doesn’t really address the original question, does it? You don’t have to pronounce all the letters in a name, so the fact that you can’t pronounce a newline isn’t sufficient to demonstrate that it can’t be part of a name.

But differently spelled names are legally distinct.

I found something about some recent-ish LG TVs having a default mode that shows static, but I couldn’t find a clear answer on why, and the way to disable it is to enable “Cable DTV”, which seems to suggest that it might actually be trying to get analogue signal by default…?

That noise is horrible; why would someone simulate it rather than just show a blue screen?
