Description: Fix the crash from #918953
 ITS Tool 2.0.4 crashes when output is redictected to a pipe, as reported in
 #918953. This comes from Python not knowing the preferred encoding for stdout,
 and using ASCII by default, therefore failing to encode anything outside of it.
 .
 This patch makes ITS Tool write to an UTF-8 encoding wrapper around stdout.
