How to write special characters like carriage return and / or newline within flogo - web ui?

Hi all,

I'm preparing a little flogo demo where one of the need is to write a file.

For this I've installed the Write File extension taken from the show cases and it works perfectly.
Fact is that I'm able to write (append mode) on a file but I don't know how to pass cr lf (or even only lf) to flogo in order to have each message per line.
I tried with "\r\n" but flogo (webui) removes those characters, same stuff with "\u000D\u000A".

If instead I try with "%x\n" then the file contains %x and then it presents the new line.
Can you please help?
