What is URL Encoding (Percent Encoding)?

URLs are permitted to contain only a specific set of characters from the US-ASCII character set. Any characters outside this set (like spaces, ampersands, slashes, or emojis) have special meaning or are invalid. URL encoding (often called percent-encoding) replaces these characters with a percentage symbol `%` followed by their hex byte values.
