I’m not a front-end developer, but I use Hugo and PaperMod for my personal site.

I noticed when going from Hugo 0.119.0 to 0.120.0, I’m seeing raw HTML character entities in my final site that are being incorrectly rendered by the browser.

The top is Hugo 0.120.0 and the bottom is 0.119.0 (nothing else changed).

I asked on Hugo's Discourse and they said it was a recent change in the delimit function in Hugo 0.120.0 and that it would require a theme update.

FWIW, I've tried the latest PaperMod hash as-of this writing and it still shows the same thing.
