Thanks.  That solved the problem for me, indirectly.

I think Dancer::Logger::Console should do that when config.yml contains 
charset: "UTF-8".

It seems that Dancer::Logger::File already does the right thing when 
inserting param() data from a UTF-8 HTML form.  I wonder why there is a 

My test case boiled things down too far.  My real issue was different. 
It was yet another case of me thinking Perl somehow tags strings with 
their source encoding, so that data coming from a UTF-8 source and going 
out to a UTF-8 sink wouldn't need translation.  I needed to add an 
explicit encode('utf-8', $s) wrapper to that code path.

Your reply was still helpful, WK, in that it reminded me that Perl 
doesn't tag encoding that way, so thanks!

As advanced as Perl is in terms of its Unicode support, it's still more 
primitive than it should be.
