Logcheck devel - Apr 2007 - How to ignore hddtemp lines that contain octal \200?

Since I upgraded from Ubuntu Edgy to Feisty, hddtemp's output to
syslog has ended in "^P?: 34 C" (for example), where the ? represents
octal \200, so hddtemp always shows up in logcheck's output; ".*"
won't match it.  I've tried copying and pasting the funny character
from syslog into the ignore pattern, and I still can't suppress this.

Any ideas?

Following the documentation's suggestion to use egrep, I've worked out
that 

$ egrep $'^\w{3} [ :0-9]{11} [._[:alnum:]-]+ hddtemp.*:.*\x80:.*$'
/var/log/syslog

shows the lines I want logcheck to ignore.  But the line

^\w{3} [ :0-9]{11} [._[:alnum:]-]+ hddtemp.*:.*\x80:.*$

in the ignore file isn't working.

What is the trick to getting logcheck to handle encoded hex values
correctly?

Thanks,
