Cannot use newline in QR Code

Hi, I am printing from a website using javascript by opening an Intent.

From what I read, it should be possible to put newline character inside the QR Code, by using %0A character. I tried many encoding like %250A and also \n, but none of them works.

I built my text in javascript, then use encodeURI as  in the example before opening the Intent.

Can you help me, thanks.
