Hi everyone,

I have a problem when I use the keyword “Update Value To Json”, I want to put a string instead of a value, it’s done but I have \ufeff and \n at the beggining and in the end of my value.

Apparently it’s related to UTF-8, is it possible to “force” UTF-8 format when I update my value?

Thank you for your help,

Brahim
