[dancer-users] Returning JSON Data

[Robert Smith]

It seems that there is still a problem with Dancer2 serializing JSON output and double encoding UTF-8 data.

I’ve thoroughly read:

https://github.com/PerlDancer/Dancer2/issues/686


https://github.com/PerlDancer/Dancer2/pull/520

Setting the options in 520 results in: "Body must be bytes and should not contain wide characters (UTF-8 strings)” error

https://github.com/PerlDancer/Dancer2/pull/647


I guess that since #686 is still open that there is no work around for those of us who need to use serializer: JSON and have UTF-8 encoded data coming from our database?
