Update escape character usage

[hanifaudah]

Hi, I found that using single back slashes don't work anymore for version 4.7.7. Double slashes work to escape the characters.

Sample code I used to prove this:

const expectedString = `{{escaped}}`
console.log('single slash escape:', handlebars.compile(`\{{escaped}}`)() == expectedString)
console.log('double slash escape:', handlebars.compile(`\\{{escaped}}`)() == expectedString)

The string literal '\\' represents string \ in JavaScript. So '\{{escaped}}' becomes {{escaped}} (escape miss) and '\\{{escaped}}' becomes \{{escaped}}.

Try:

console.log(`\{{escaped}}`)  // {{escaped}}
console.log(`\\{{escaped}}`) // \{{escaped}}

If you're not familiar with JavaScript:

• Text formatting - MDN
• String literals - Lexical grammar - MDN
• Character escape - MDN

I see, thanks for the feedback.
