Hi, we came across this case where we are basically cloning outline

where the original outline title is a UTF16BE encoded text string
containing the value 00A0 (non break space). We later use the string to
assign the title in a new outline item and the A0 is recognised as a 
€ sign.

Here is a simple test:

 COSString victim = COSString
.parseHex("FEFF004300680061007000740065007200A0");
 PDOutlineItem node = new PDOutlineItem();
 node.setTitle(victim.getString());

If you look at the node dictionary you'll see that the title value is

I'm talking about the node dictionary, try adding this:
System.out.println(node.getTitle());
