+\$escape\_html {#variable.escape.html}
+==============
+
+Setting `$escape_html` to TRUE will escape all template variable output
+by wrapping it in
+`htmlspecialchars({$output}, ENT_QUOTES, SMARTY_RESOURCE_CHAR_SET);`,
+which is the same as `{$variable|escape:"html"}`.
+
+Template designers can choose to selectively disable this feature by
+adding the `nofilter` flag: `{$variable nofilter}`.
+
+Modifiers and Filters are run in the following order: modifier,
+default\_modifier, \$escape\_html, registered variable filters,
+autoloaded variable filters, template instance\'s variable filters.
+Everything except the individual modifier can be disabled with the
+`nofilter` flag.
+
+> **Note**
+>
+> This is a compile time option. If you change the setting you must make
+> sure that the templates get recompiled.
