I've been running this today - standalone on localhost port 80 with the
built in CherryPy web server on my mail store. First impressions are it's
terrific :-) As my intended 'target' mail store will be geared towards a
'internal work stuff knowledge collection', lots of emails contain html
links to intranet pages and sites. I can adapt the bleach usage to suit (or
just remove it), but along the way of searching and viewing mail, I've
encountered quite a few occurrences of failing to UnicodeEncode. An example
backtrace looks like this:

I'm no Python expert, but from a quick google it would seem like the cause
of such an exception is related to not using utf-8.

Brian - do you think something needs modifying in nmweb.py to cater for
this type of thing, or is this somehow related my own mailstore (not sure
why that would be as my messages haven't been modified).
Cheers,
