Seems that you can reproduce the bug on demand. So can you please try
the following:

1. Install the attached Encoding.pm file as /usr/share/perl5/DebConf/Encoding.pm
   (This instruments the calls to WrapI18N so we can see what text is
   making it fail.)
2. Run the `script` command to take a typescript.
3. Run apt-get again to reproduce the problem.
4. Reply with the typescript.
