The wire posting problem

I got a problem here, probably the topic explains it self but ill explain more in details.

When Repeating a Letter for lets say the max chars allowed i get this problem:

and this is not only on the wire, Its also on questions and message board. Any idea how to solve that?

Also i want to ask if i can extend the wire plugin to actually Reply on the same page instead of going to a new page to post a reply, More of like the Status of facebook where when u click on the reply it automatically uploads it without having to go a new page.
