+Description: Fix the crash from #912099
+ ITS Tool 2.0.4 crashes when building some documentation, as reported in
+ #912099. This comes from translations with invalid XML markup, which ITS Tool
+ fails to merge (which is not abnormal), and to report these issues, needlessly
+ encodes the original msgstr from unicode to bytes, causing it to be recoded
+ using the default ascii codec, which fails when the msgstr contains anything
+ out of ascii.
+ .
+ This patch removes the useless decoding, avoiding the failing subsequent
+ recoding. It also explicitly encodes the output strings to be able to print
+ them in all cases, even when the output encoding cannot be detected.
