Python helpfully uses a sensible locale when stdout is a tty but uses
the system (not the filesystem) default encoding, which may be ascii
and unable to encode some of the data we need to save. So brute force
kludge it to ensure emit.encoding is UTF-8 when writing the output
we'll read as UTF-8 anyway.
(This matches dev's commit 0ef79d94f6
for the reworked version of the script.)
