About this URL Encode
URL Encode converts special characters into percent-encoded sequences so the text can be safely used in URLs and query parameters.
This is useful when building links, working with query strings, or pasting values into APIs. If you only need to encode a query value, encodeURIComponent-style behavior is usually preferred.
