Frequently Asked Questions
What characters need encoding?
Reserved characters like ampersand, equals, question mark, slash, hash and spaces must be encoded. Non-ASCII characters including accents and Unicode also need encoding.
What is the difference between encodeURI and encodeURIComponent?
encodeURI preserves URL structure characters. encodeURIComponent encodes everything except letters, digits, and a few symbols, suitable for parameter values.
Is double encoding a problem?
Yes. Double encoding turns %20 into %2520. Always paste original unencoded text for encoding, or the encoded version for decoding.
