How to escape curly braces?

[kirschkern]

In my localized string I have double curly braces like this:

"defaultMailContent" : "Hello {{USER_NAME}},\n\n\nRegards",

When running this, the parser throws an error in the console:

Message compilation error: Not allowed nest placeholder
1  |  Hello {{USER_NAME}},

I've tried to escape the {{ using a backslash "\" but this doesn't change anything.

How can I use {{ and }} within my string and tell the parser to not translate it?

{{ data }}

I don't understand your answer. May you give a full example?
