HTML and Encoded Characters with Handlebars

As soon as I updated some of the templating on one of my websites to handlebars, HTML code wasn’t being rendered, and I recieved odd characters in the output, like:
 

My Blog Name » Blog Sub Title

The solution to this is instead of using the standard double bracket to insert the content, use triple brackets (I don’t know why, must be telling the templating engine to render the character codes as html):
 

<h1>{{{Blog-Title}}}</h1>

Once I figured this out, the solution is easy.  Unfortunately it took some time to track down, since I first suspected that the issue was caused with some of the php code somewhere, the encoding of the database, etc…
