+  # Extends `#escape_html` to support escape modes. By default all strings
+  # are escaped on `&`, `>` and `<`. Add the `:nonstandard` mode to omit
+  # this conversion.
+  #
+  # If no mode is given then the `:default` mode is used.
+  #
+  # Available modes include:
+  # * `:quote`     - escapes single and double quotes
+  # * `:newlines`  - escapes newline characters (\r and \n)
+  # * `:ampersand` - escapes the ampersand sign
+  # * `:brackets`  - escapes less-than and greater-than signs
+  # * `:default`   - escapes double quotes
+  #
+  # @example
+  #   escape_html("<tag>")  #=> "&lt;tag&gt;"
+  #   escape_html("Example\nString", :newlines)  #=> "Example&#13;&#10;String"
+  #   escape_html("\"QUOTE\"", false)  #=> "\"QUOTE\""
