The problem is not the break tag. The problem is you have a character along with the text within the quotes. The character only shows up on PC but is not shown on Mac.
Hei Mike, your absolutely right. I can see the character in my text editor on the Mac, too. Must be a copy and paste issue - copied the text from Illustrator… Works perfectly now. I also learned from my colleague, that the correct form to set the br-tag is this way: br / Thanks a lot!! Regards, Kalle
