Subject: non-printable characters in /proc/interrupts

I've wondering about this entry at my ThinkPad T400 (kernel 2.6.39.1):

n22 ~ # grep 47: /proc/interrupts
 47:      44041      69740   PCI-MSI-edge      l▒��@�E�

I attached the output of 
$>grep 47: /proc/interrupts > /tmp/int47
onto this email, the complete table looks like this :

n22 ~ # cat /proc/interrupts
