Why do URLs need encoding?

URLs can only contain certain characters. Encoding replaces unsafe characters (like spaces) with % sequences.

What is URL Decoding?

URL decoding reverses percent-encoding, replacing %XX sequences with their original characters. This makes encoded URLs and query strings human-readable.
