Do you have some copy/paste-able snippet to test on?

Doing:

'Testing·';

'Testing·';

Doesn't cause the error; although this package doesn't work with unicode characters (different issue)

Also, what are your highlight selected settings?

[ggl]

Yes. Scroll over the \u part. frag.appendChild(document.createTextNode('\u00A0'));

👍 Thanks.

Blows up when Only Highlight Whole Words is not ticked.
