Might be fixed via #8

Do you mind sharing some screenshot/screencasting? I looked at your example, and it seems to be rendering properly for me. The non-printable characters inside the quotes are there, and caret behaves identically when going through them in both playgrounds.

Should have mentioned I'm using firefox 55.0.3 https://www.youtube.com/watch?v=xbss4NGHWxM

Thanks. I can reproduce this in FF. This happens because FF renders these characters differently in the textarea and in the regular HTML (which rather looks like a bug on FF side). If you disable syntax highlighting in settings in Go Play Space, you will see what I mean. Not sure if this is fixable on my side, unless I completely change the editor component.
