Can't download a channel with spaces in user name

[kurogetsusai]

Can't download a channel with spaces in user name. I tried to escape them or inserting a %20 instead, but nothing works. Is there a workaround to do it?

$ youtube-dl --verbose -ciw 'ytuser:Raon Lee'

My version:

$ youtube-dl --version
2015.06.04.1

A package from Ubuntu 15.10's repo.

Use full channel URL.

How? It doesn't work either:

Okay, it works now, thanks! I should have tried it before opening an issue, sorry.
