[dancer-users] D1 => D2 from_yaml has changed

[Sawyer X]

With Dancer 1 we kind of just tried to make it work, while with Dancer2 we
have a much (hopefully) clearer way to handle it in the way that works with
Perl:

* Decode to Perl representation when receiving input.
* Encode to UTF-8 from Perl representation when producing output.

Thus:
* Serializers are expected to encode by themselves.
* Template renderers also have the responsibility to encode to whatever
encoding they want (usually UTF-8).

A few emerging guides on this matter, outside the scope of Dancer:
https://github.com/rgs/p5-intelligible-unicode/
http://dev.perltuts.com/tutorials/unicode-introduction
https://github.com/Perl/perl5/compare/blead...rjbs/unicook

I'm sure you know more on this topic than us though. :)
