在 jsfuck 中获取“C”字母的替代方法

目前jsfuck使用以下代码来获取“C”字符

console.log(
    Function("return escape")()(("")["italics"]())[2],
)
   
console.log(  // after expansion
    []["flat"]["constructor"]("return escape")()(([]+[])["italics"]())[!![]+!![]]
)

console.log(  // after final strings expansion we get pure jsfuck code

但是这种方法使用了不推荐使用的函数"".italics （信息在这里）。我开发了一个小工具并试图找到一些基于的替代方案，btoa但我遗憾地发现 node.js 不支持（在线）

console.log(
  Function("return btoa")()("t.")[1]
)

console.log( // after expansion
  []["flat"]["constructor"]("return btoa")()("t.")[+!![]]
)

console.log( // after full expansion

有没有办法（在当前版本的 chrome、safari、firefox 和 node.js 上工作）使用 jsfuck 但不使用不推荐使用的方法来获取字符“C”？
