Good Day Monks,

I have been breathing too deeply from the fumes of the Perl Unicode documentation.
I find myself dizzy and in the need of guidance.

The following is from 
       http://perldoc.perl.org/perluniintro.html

and in particular the subsection entitled: Displaying Unicode As Text:

Sometimes you might want to display Perl scalars containing Unicode as simple ASCII (or EBCDIC) text. The following subroutine converts its argument so that Unicode characters with code points greater than 255 are displayed as \x{...} , control characters (like \n ) are displayed as \x.. , and the rest of the characters as themselves: 
    sub nice_string {
        join("",
            map { $_ > 255 ? 
                sprintf("\\x{%04X}", $_) :  
                chr($_) =~ /[[:cntrl:]]/ ? 
                sprintf("\\x%02X", $_) :    
                quotemeta(chr($_))         
            } unpack("W*", $_[0])
         )           
     }

My question is this: How do you undo that operation to recover the original scalar?
