Merge pull request #659 from evetsso/devel

Conditional CherryPy latin-1 workaround
(httphandler: don't assume filenames are latin-1 when transcoding)

I rewrote the change to keep the code, but only run it when beneficial,
and unfortunately made my own commit for it. Performing this as an empty
merge from @evetsso's PR commit to give hom credit.
