[dancer-users] Best practice to escape HTML entities in Dancer2 and TT

Why not use TT’s native FILTER capability:
<% somehtml FILTER html %>
From an MVC perspective it’s probably the right place to do html escaping — not at the lib (Model) level.
You can also pipe additional filters:
<% somehtml FILTER html | html_line_break | more filters %>
