URL Encoder

Anything that isn't a URL-safe character gets percent-encoded — spaces become %20, & becomes %26, non-ASCII letters become their UTF-8 percent-encoded bytes, and so on, using the browser's built-in encodeURIComponent function.

Only encode individual components — a query parameter value or path segment — not an entire URL with its protocol and slashes, since encoding the slashes and colons would break the URL structure.

That's the percent-encoded form required inside a URL; spaces and reserved characters like & (which separates query parameters) must be encoded when they appear as literal data rather than as URL syntax.

Yes — encodeURIComponent converts any Unicode character to its UTF-8 byte sequence and percent-encodes each byte, so emoji, accented letters, and non-Latin scripts all encode correctly.
