将Uint8Array转换为javascript中的字符串（带有中文字符）

Question

I am using the following code to convert a Uint8Array object to string:

var fileData = cc.FileUtils.getInstance().getByteArrayFromFile("file.txt");

// fileData is a Uint8Array object
var dataString = "";
for(i = 0; i < fileData.length; i++) {
    dataString += String.fromCharCode(fileData[i]);
}
alert(dataString);

and if the content of the "file.txt" is latin characters say

"this is a watch"

then the codes above works fine.

But, if there is non latin characters in the file say "thank you 谢谢"

then the convert result is not correct.

Hope someone can help me, thanks :)

Answer 1

Not the solution, but to find the problem please verify the array by getting the character codes like this

var str= "thank you 谢谢";
for(i = 0; i < str.length; i++) {
    console.log(str.charCodeAt(i));
}

EDIT:

As it is giving 34 for 35874 it is clear that the character code is not coming in 16 bits. Because

35874 = 10001100 00100010 => in 8 bits => 00100010 = 34

Please check the encoding of the file. Also see whether you can specify the encoding in getByteArrayFromFile . Usually a charset is used to read multiple bytes as you can see in this as an example - actionscript function
