Smart Punctuation Extension
SmartPunctExtension Intelligently converts ASCII quotes, dashes, and ellipses to their Unicode equivalents.
For example, this Markdown…
"CommonMark is the PHP League's Markdown parser," she said. "It's super-configurable... you can even use additional extensions to expand its capabilities -- just like this one!"
Will result in this HTML:
<p>“CommonMark is the PHP League’s Markdown parser,” she said. “It’s super-configurable… you can even use additional extensions to expand its capabilities – just like this one!”</p>
This extension is bundled with
