在字符串Javascript中搜索希腊字母

Question

I'm trying to figure out a way to search for a Greek letter in a string replace it with another character. For example

value = "Hello μ!";
value.replace("μ", "You");
alert(value);

//Alerted value should be "Hello You!"

Unfortunately this isn't working. I tried searching for answers online but to no avail. Any help will be greatly appreciated. Thanks for the help in advance.

You have to reassign the value. The replace function does not modify the existing value because strings are immutable in Javascript. This works:

value = value.replace("μ", "You")

 value = "Hello μ!"; value = value.replace("μ", "You"); alert(value);
