Description

Added an example showing that normal text characters can also be percent-encoded, even if they don't have to.

Motivation

const hex = [];
hex.length = 256;
for (let i = 0; i < 256; i++) {
  hex[i] = i.toString(16).padStart(2, "0");
}
console.log(hex);
fetch(`data:application/octet-stream;,%${hex.join("%")}`)
  .then((resp) => resp.arrayBuffer())
  .then((buf) => {
    const bytes = new Uint8Array(buf);
    console.log([...bytes]);
    for (let i = 0; i < 256; i++) {
      if (bytes[i] !== i) {
        console.log(`buf[${i}] !== ${i}`);
      }
    }
    console.log("finished");
  });

Thanks, @Worldwidebrine.

As you'll see from my comments below, I did find the addition a little confusing. If I've totally misunderstood this, maybe you can explain your motivation a bit more, to help me understand.
