Mdless is blocking and consuming 100% CPU

The following input is causing mdless to block for a long time (possibly forever)

# Hello world




  

Hello –

Have tried to cut replace/down some parts, however removing some substrings like Hello – or ~~~~~ makes the text readable by mdless, so had to post this weird piece of text 😀

Killing with ctrl+c results in:

It's the dash in 'Hello —'. If you change that to a regular hyphen (or a couple of them if you want an en-dash) it works properly. I'm not sure offhand where that's hanging it up, will check into it when I get a chance.
