Decoding sig packet data

[Nicholas Cole]

Does anyone have any advice about decoding the 'octets' in the last
field of the spk lines of the --with-colons output.  The notation
appears non-standard.  The only python library, for example, that I
can see that deals with 'percent encoded' octets is the urllib
library, but that library's 'decode' function outputs gibberish.

I know, of course, that the answer will be something completely
obvious, but for the moment I'm completely stumped!

Best wishes,

Nicholas
