I thought the problem was Rails safe buffers

gistfile1.rb

# Assuming that :something is trusted

Mustache.render("<h1>template</h1> {{ something }}", {:something => "<h2>Testing</h2>" })

# => <h1>template</h1> &lt;h2&gt;Testing&lt;/h2&gt;

# Desired out is "<h1>template</h1> <h2>Testing</h2>"

# Solution, use the triple mustache - {{{ }}} - for content that shouldn't be escapes

Mustache.render("<h1>template</h1> {{{ something }}}", {:something => "<h2>Testing</h2>" })

# => <h1>template</h1> <h2>Testing</h2>
