Failed to use the --username switch in Hashcat 3.20 on OS X

[atom]

There's something wrong for sure. Don't you see this difference?

--session

and

—-username

While both kind of look like a hyphen/minus, the second one is different. Such problem usually are created when copy/paste a string from a html source, maybe a website/blog post or an email. It's clearly not a minus char. Since getops can't recognize it as an option it must be the hash, because the hash/hashlist is always the first argument that is not an option.
