8va line bug

I’m not sure how you got this with a line length of zero, but did you see this post, indicating that you could use a custom Playing Technique?:

8va symbol? Symbol for octave

Where can I find an 8va symbol? To indicate that the notes displayed are actually played one octave higher. And also something to stop the 8va, I din’t quite remember, loco maybe?
