Escape HTML markup in template variables. By default is false (don't escape HTML).
jSmart.prototype.escape_html = true; //set global for all jSmart instances
var t = new jSmart('{$bold}');
t.escape_html = true; //... or set for this instance only, overrides jSmart.prototype.escape_html
t.fetch({bold: '<b>test</b>'});
Output:
<b>test</b>
