Issue decoding a string

[tmmls]

Hi,

I'm having issues decoding a string ...

var newText = "This is a [u0027] test";
newText = newText.replace("\[u", '\\u');
newText = newText.replace("]", "");
newText = decodeURI(newText);
alert(newText);

The base string contains square brackets and lacks the backspace prefix.

This however seem to work ...

var newText = "This is a \u0027 test";
newText = decodeURI(newText);

alert(newText);

Does aynone have a solution?

Thanx

I think no need to escape [ in first replace? Or escape ] in second replace?

[tmmls]

the replacement of the brackets works fine. But it doesn't seem to decode the result ...

To get a string from a Unicode number you'd use 

String.fromCharCode (0x0027);

You can't use this construct as the replacement value in a replace() call, but you can use a function as the replacement parameter:

var newText = "This is a [u0027] test";
newText = newText.replace (/\[u(....)\]/, function () {
  return String.fromCharCode ('0x'+arguments[1]);
});
newText = decodeURI(newText);
alert(newText);

But in fact there is no need to decodeURI newText, you can delete than line.
