Let’s just make a new text standard, call it “tinychar” or something. You don’t need any personal notes when it’s a known concept

We should all make up our personal character systems so we won’t have to worry about this situation /s

Also, 1024 characters assumes you are just using ASCII, which has a bunch of control codes and characters of other languages you won’t use. If you trim these and remove uppercase letters you could probably make your own custom letter set that fits 2 characters in a byte, doubling your information to make it 2048 chars

It isn’t. There was a story a few weeks ago of one getting pulled off the streets of england because it was missing required papers for imported cars. I’m rather sure it won’t be able to get those papers because it’s not considered road safe in europe. Let’s go safety regulations and customer protections!
