Hi iRedMail people.  My question today is not really related directly to iRedMail functionality.
I just wanted to ask you what I may be missing in my terminal (Putty) or SSH settings that causes the installation forms draw strange characters instead of lines?  Why do I get all these xxxxxx and qqqq substitutes for the lines?

Thanks
