String that contains all ascii characters

My javascript is a bit rusty, but something like this:

s = '';
for( var i = 32; i <= 126; i++ )
{
    s += String.fromCharCode( i );
}

Not sure if the range is correct though.

Edit:
Seems it should be 32 to 127 then. Adjusted.

Edit 2:
Since char 127 isn't a printable character either, we'll have to narrow it down to 32 <= c <= 126, in stead of 32 <= c <= 127.

var s = ' !"#$%&\'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~';
