Print a backslash in Unicode via perl

Hi!

When I print out unicode glyphs from a font everything is fine, aside 
from  the backslash:

use Image::Magick;
$image = Image::Magick->new;
$image->Set(size=>'150x150');
$image->ReadImage('xc:white');
$image->Annotate(font=>"times.ttf", 
pointsize=>30,align=>Left,fill=>'black', x=>50, y=>50, text=>"\x{005b} 
\x{005c} \x{005d}");
$image_name="backslash.gif";
$image->Write(filename=>$image_name);

The font has a backslash on the position 005c (I used the times.ttf that 
came with Windows) and checked it in a font editor.
Can anybody tell me what I am doing wrong? Should this backslash also be 
somehow escaped and if yes, how?

Thanks a lot in advance,
Dani
