How to replace ASCII code (alt+207) in JavaScript?

I have a string which contains square boxes(I found it's开发者_如何学Python ascii code as alt+207)...

How can I replace this with ' '(a single space).

I am assuming you mean the character: ¤

If so, you could try,

str = str.replace('\u00A4', ' ');

Or if you want to do it to any character that is not ASCII, you could try something like:

str = str.replace(/[^\u000A\u0020-\u007E]/g, ' ');

Is it one of these characters? ▪ = ▪ or ■ = ■

If so, you can do this

var str ="Something ▪ and ■";
str = str.replace(/▪|■/g, " ");
document.write(str);
