Characters that cannot be used in URLs (such as Japanese or spaces) are replaced with forms like %E3….
Decoding turns them back into the original characters.

Notes

"A part of a URL" also converts ? & and =. Use it to put search words into a URL.
"A whole URL" keeps ? and &. Use it to fix only the non-ASCII parts of an existing URL.
