[Question] How to output a form feed character in a template

[klreeher]

I have a handlebars template that looks like so:

{{#each thing}}
... bunch of straight forward templating ...
{{/each}}
{{{formFeed}}}

The form feed character is \f or https://unicodeplus.com/U+000C
I need my list of things to be output with a form feed character after each thing gets templated. I've tried a couple different things, including:

template:

{{#each thing}}
... bunch of straight forward templating ...
{{/each}}
{{{\f}}}

None of these, when I write the compiled text to file, actually have the form feed character.

I've tried tackling this through the writing to file side, thinking it was something there, but if I only template the thing section and write the form feed character like this, it works:

            using (StreamWriter sw = new StreamWriter(File.Open(outputFile, FileMode.CreateNew), Encoding.Unicode))
            {
                foreach (var thing in thingData)
                {
                    var text = RenderThing(ticket); // this is the handlebars.compile(template + data)
                    sw.WriteLine(text);
                    sw.WriteLine("\f");
                }

            }

This is not an ideal solution because one of the values the template uses for the looped things is the index of the thing in the list, but I can't figure out how to get the template to actually include the real form feed character.

If I pass the formfeed character in with the template data, like this:

        public string RenderThing(List<ThingObject> thingData)
        {
            string compileText = "{{> " + _templateName + "}}";
            _patternTemplate ??= _handlebars.Compile(compileText);

            var data = new
            {
                tickets = thingData,
                formFeed = "\f"
            };

            var text = _patternTemplate(data);
            return text;
        }

and I have the {{{formFeed}}} outside the #each loop, then I can get the form feed character to show up at the end. But if I try to move it into the loop, it's not rendered.
