Must HTML entities require safeHTML filter?

I’ve recently migrated my website from Jekyll to Hugo and I’m using my own custom theme.

Especially on mobile some of my article titles have words a bit too long, so I have added a couple of soft-hyphenation HTML entities (­). Because of this I had to add a safeHTML filter for these outputs, which had me wondering: would it be harmful if HTML entities were accepted and parsed by default?

What do you think?
