C++ array of char using unique_ptr

First of all, I know this is not the best way to do this, I'm just looking how it should be done. I created a class called bord,which holds a member

        std::unique_ptr<std::unique_ptr<char>[] > char_bord;

Which should be the correct syntax, then I try to initialize this in the constructor:

bord::bord():char_bord(new std::unique_ptr<char>[10])
{
    //char_bord=new std::unique_ptr<char>[10]; //This did not seem to work aswell.
    for(int i=0;i<10;i++)
      char_bord[i]=new std::unique_ptr<char>[](new char[10]); 
    return;
}

This results in the following heap of errors, which I did not manage to decipher.

What am I doing wrong, assuming I am doing something wrong.
