FAQ

What's the difference between encodeURI and encodeURIComponent?

encodeURI does not encode ; , / ? : @ & = + $ - _ . ! ~ * ' ( ) #, making it suitable for encoding a whole URL; encodeURIComponent encodes more characters (including /?&=), making it suitable for encoding a single parameter value, so an & inside the value isn't mistaken for a separator.

What if decoding fails?

It's usually because the string contains a lone % (not in %XX form). Check your input, or encode it first and then decode it to verify.
