When logging a character such as "™" to the console, the following error is produced:

[28211] error @0.011815> [hit #1]request to GET /foo crashed: Warning caught during route execution: Wide character in print at .../perl5/lib/perl5/Dancer/Logger/Console.

Example:

get '/foo' => sub {
    debug "testing™";
    return bar;
};
