I’m not sure when it started happening – maybe it has been there all along – but is now something that is increasingly annoying me (something seen, cannot be unseen and all that!)…
When typing the “em-dash”, which I do frequently, by means of the “alt±” combination, it is followed (more-often-than-not) by a little ‘caret’/space-character, as per the screengrab below…
Did not know about the ‘non-breaking space’ – that’s the culprit right there. Or rather, my sloppy typing is the culprit. I was hitting the spacebar too quickly, in other words, before releasing OPT – hence the n-b-s!
So obvious in hindsight, but couldn’t for the life of me work out what was happening, since it seemed to be happening randomly (which is was, or rather – the pattern was !)
