[Josh-Cena]

This sentence should be rewritten as:

The encoding performs substitution: each encoded character is replaced with a '%' followed by the hexadecimal representation of its ASCII value.

Furthermore this article says nothing about how non-ASCII characters are encoded, so we should add another sentence akin to:

For non-{{Glossary("ASCII")}} characters, their {{Glossary("UTF-8")}} encoding is encoded byte by byte.
