Mandrill - Send HTML tags inside X-MC-MergeVars

I tried to send HTML tags inside X-MC-MergeVars for my Mandrill handlebar template, but doesn't seem to work.

PHP part: 

[...]
$message->getHeaders()->addTextHeader("X-MC-MergeVars", json_encode(["foo" => "b<strong>a</strong>r"]));

Mandrill template part:

Here is my var b<strong>a</strong>r

Thank you
