I have a string with invalid XML code point

var o = { name: "A\u0002B" }

And Handlebars.js template: {{name}} which outputs the string unchanged with U+0002 character between A and B. A web browser display such HTML somehow, but HTML validation https://validator.w3.org/nu/#textarea fails with: "Error: Forbidden code point U+0002".

Is there any way how to make double braces to sanitise such input, e.g. replace invalid code points by Unicode replace char U+FFFD ? If not, is it possible to make a runtime option for that?
