DataWeave 2.1 is compatible with Mule 4.1. Standard Support for Mule 4.1 ended on November 2, 2020, and this version of Mule will reach its End of Life on November 2, 2022, when Extended Support ends.

Deployments of new applications to CloudHub that use this version of Mule are no longer allowed. Only in-place updates to applications are permitted.

MuleSoft recommends that you upgrade to the latest version of Mule 4 that is in Standard Support so that your applications run with the latest fixes and security enhancements.

encodeURI(String): String

Encodes a URI with UTF-8 escape sequences.

Applies up to four escape sequences for characters composed of two "surrogate" characters. The function assumes that the URI is a complete URI, so it does not encode reserved characters that have special meaning.

The function does not encode these characters with UTF-8 escape sequences:

Type (not escaped) Examples

Reserved characters

; , / ? : @ & = $

Unescaped characters

alphabetic, decimal digits, - _ . ! ~ * ' ( )

Number sign



Name Description


The URI to encode.


This example shows encodes spaces in one URL and lists some characters that do not get encoded in the not_encoded string.


    "encodeURI" : encodeURI("http://asd/ text to decode /text"),
    "not_encoded": encodeURI("http://:;,/?:@&=\$_-_.!~*'()")


   "encodeURI": "http://asd/%20text%20to%20decode%20/%25/\"\'/text",
   "not_encoded": "http://:;,/?:@&=$_-_.!~*'()"
