Locale-Sensitive JavaScript Method

unescape(string);


Internationalization (I18n) Method Overview

The unescape method returns a copy of string that has been encoded using escape. unescape converts single and double hexadecimal encoded values back to their display values, supporting all Unicode characters, even those outside the the Basic Multilingual Plane (BMP), which require two 16-bit values (e.g. %uD840%uDC10).

In the following example, the Chinese character and spaces have been replaced with their hexadecimal encoded values:

var str = "%u6F22One%20Two%20Three%uD840%uDC10";
var result = escape(str);

Method returns:

result: 漢One Two Three𠀐
