This is a (sub-)trivial issue, but I stumbled upon the fact that then non-entity ‐ behaves differently in the post preview than in Discourse.
In a draft post:
check out this ‐
Seen in the preview:
check out this -
Once submitted:
check out this ‐
While it may be a convenient entity, I don’t believe ‐
is a standard HTML entity (most sites suggest -
if you need an entity for a hyphen), so the post preview should probably not be converting ‐
to a hyphen.
Just in case someone is really bored and looking for a “bug” to fix. Then again, the preview rendering may be handled by a separate library and them’s the breaks.
