The encodeURI() function does not encode characters that have special meaning (reserved characters) for a URI. Both encodeURI() and encodeURIComponent() do not encode the characters -.!~*'(), known as "unreserved marks", which do not have a reserved purpose but are allowed in a URI "as is". The characters on the second line are characters that may be part of the URI syntax, and are only escaped by encodeURIComponent(). Because lone surrogates in UTF-16 do not encode any valid Unicode character, they cause encodeURI() to throw a URIError.ĮncodeURI() escapes all characters except: A–Z a–z 0–9 - _.

The encodeURI() function escapes characters by UTF-8 code units, with each octet encoded in the format %XX, left-padded with 0 if necessary.

Javascript has a built-in function named atob() which performs Base64 decoding.
