Question

Unable to pass special characters unicode value to REST activity

1

Hi , I am calling a POST REST API where in the body I need to pass [special character+”SomeString”]. The special character’s unicode value is ‘\u0091’ (this editor does not supports the special character. it is a question mark wrapped inside a square) In my microflow I am creating a string variable appending spl. char and the string. However the unicode value is not converted into special character but instead mendix treats it as a complete string. While debugging I realized that mendix is implicitly adding one extra ‘\’ to the unicode ‘\u0091’ to avoid escaping the ‘\’ part in the unicode and this is making it act as a complete string. How do I escape the entire string(\u0091) so that it will be converted to the special character . Note: I tried passing the actual spl. character in the body but it does not work. this is the special character. Thanks in Advance, Aditya

Hey Aditya,

Whenever you want to send something over a REST call, you need to encode you string. In this case the � can be encoded to ‘%EF%BF%BD’
So in you case you would have ‘%EF%BF%BD’+’PackagingSN’.

If you want to dynamically encode your string in a microflow you can do so by changing the string with urlEncode($StringToEncode). See mendix documentation for more information.
