Hi @Lychee,
You can do it with backslashes. Like this:
{{ `\{\{ it's all just a string \}\}` }}
I'm not using quotes/single quotes, I'm using backticks to wrap the string, otherwise you'd need to escape your apostrophe's as well.
Alternatively, you could use &123; and &125; instead, which will render the same way, and then you don't have to put them in curly braces in the first place.
