You didn't provide any information on the bug (just your workaround for it). If you want us to help resolve your problem, you'll need to at least describe it to us.

For starters, what output do you get and what output do you expect? It's best if you avoid "non-ASCII" characters by using tools that escape these (Data::Dumper with $Data::Dumper::Useqq=1;, od command line tool, etc)
