There should be no need to change your apps charset.

If you look at any of the HTTP specs, a Content-Type header looks like:

   Content-Type: text/html; charset=utf-8

Without digging into the Dancer1 code,

   send_file(\$str, content_type => 'text/html; charset=utf-8', filename 
=> 'foo.html' );

should DWIM (it will in Dancer2). Substitute your own mime types and 
encoding as needed.


Hope that helps,
