Twig: Template outputting only "0" don't render anything

[ericmorand]

Consider the following template:

0

Rendering that template outputs nothing:

https://twigfiddle.com/ayv6cz

The compiled template looks like this:

protected function doDisplay(array $context, array $blocks = [])
    {
        $macros = $this->macros;
        // line 1
        echo "0";
    }

This is strange: echoing 0 or "0" in PHP ouputs "0".

Maybe that's just an issue of twigfiddle.com.

[ericmorand]

Good point. Let me check with command line.

@xabbuh You are absolutely right. It works ex expected from the command line. Closing this issue and opening one on twigfiddle repository. Thanks for your help.

Apologies for the noise.
