Javascript regex unable to replace certain special characters

Question

I have this Javascript regex:

 body = body.replace(/[\x80-\xFF]/g,"#");

which I am hoping to use to replace characters in the table here . However I am unable to replace the characters highlighted in red on the table in that page. I couldn't comprehend why. Can someone enlighten me on why it is happening like that and what the workaround? Thank you.

一种解决方法是改用Unicode范围，当我在控制台的示例页面上尝试此方法时（我认为您要这样做）：

document.body.innerHTML = document.body.innerHTML.replace(/[\u0152-\u2122]/g,"#");
