My html output is including a lot of these unicode characters: 
These characters appear between partials and shortcodes.
I’ve only noticed this happen when nesting partials in shortcodes or partials in partials.
shortcodes/Map.html:
--more above-- {{ range where .Site.Pages "Section" "chapter" }} {{ partial "Tooltip.html" . }} {{ end }} --more below--
partials/Tooltip.html:
`
{{ .Title }}
A screenshot of the output in dev tools:
This amounts to whitespace and that’s normally not an issue. But it’s causing a real headache when using flexbox. Flexbox counts those characters as flex items and there are unwanted gaps between the real items.
