Since the last Discourse update, when I write a post title that contains a quote ', it is converted to › preceded by a single space when I create the post.
If I click on the edit title button, the input correctly shows ' but it is always converted to › (preceded by a single space) when I do confirm the title edition.
We might have to revert that commit, since our HtmlPrettify is working on a “character-by-character” basis, it doesn’t know when a quote is the start of a matching pair or merely an apostrophe.
