[Dancer-users] Problem with PLACK

[Alex Kapranoff]

Hello, Igor!

I can repeat your problem using your directions. Looks like
Plack::Middleware::Lint got enabled by default in development environments
somewhere in April and together with Dancer::Template::TemplateToolkit it
leads to your error.

There is a simple way to workaround the error. You may switch to
Template::Simple by commenting out "template" setting in config.yml.

Proper fix would be to apply this patch to your Dancer:
diff --git a/lib/Dancer/Template/TemplateToolkit.pm
b/lib/Dancer/Template/Templa
index 0e092db..4bdb717 100644
--- a/lib/Dancer/Template/TemplateToolkit.pm
+++ b/lib/Dancer/Template/TemplateToolkit.pm
@@ -19,6 +19,7 @@ sub init {
     my $tt_config = {
         ANYCASE   => 1,
         ABSOLUTE  => 1,
+        ENCODING  => 'utf8',
         %{$self->config},
     };

And then specify "charset: utf8" in config.yml.

(to all: we should think about making charset: utf8 the default)

Igor, can you test it?
