It's not needed because the change topic information already comes
from the GET /change/ID/details REST call.

Make IO encoding/decoding locale-based

This two pragmas are suggested in the perllocale's section 'Unicode
and UTF-8'. They're fully implemented on Perl 5.16 but I tested it on
Perl 5.10 and it seems to work right. At least with my pt_BR.UTF-8
locale.

still format the output using printf formats.
