Convert integer array to string at javascript

javascript, utf-8

Solution

JavaScript strings consist of UTF-16 code units, yet the numbers in your array are the bytes of a UTF-8 string. Here is one way to convert the string, which uses the decodeURIComponent() function:

var i, str = '';

for (i = 0; i < arr.length; i++) {
    str += '%' + ('0' + arr[i].toString(16)).slice(-2);
}
str = decodeURIComponent(str);

Performing the UTF-8 to UTF-16 conversion in the conventional way is likely to be more efficient but would require more code.

Problem

Here is php code: ``` $arr=array(228,184,173,230,150,135,99,104,105,110,101,115,101); $str=''; foreach ($arr as $i){ $str.=chr($i); } print $str; ``` the output is: `中文chinese` Here is javascript code: ``` var arr=[228,184,173,230,150,135,99,104,105,110,101,115,101]; var str=''; for (i in arr){ str+=String.fromCharCode(arr[i]); } console.log(str); ``` the output is: `中æchinese` So how should I process the array at javascript?
