Strange web request

["Nexus" <nexus () patrol i-way co uk>]

Hi folks,
    Has anyone seen a request like this before ?   It's either a l33t0 trick
or some seriously broken code; since I've never seen this sequence before I
was curious of anyone else has.   This hit an sshd listening on port 80 btw,
source IP obviously changed ;-)

Cheers.
