How Do I Convert Gbk To Utf8 With Pure Javascript?

I want to load some text from other site which the content is GBK encoded, but my site is UTF8. Is there anyway by which I can convert these GBK text into UTF8 for display? For som

Solution 1:

There is a javascript to convert between gbk and unicode: which maps all the 21886 gbk Chinese chars to unicode

You can simply download the javascript file , include it and using : unicode to gbk:

$URL.encode(unicode_string)

or gbk to unicode:

$URL.decode(gbk_string)

I tested it. It's working well on my web : zhuhaiyang.sinaapp.com/base64/index.html

which do base64 ency using pure javascript.

For chrome or firefox, you could use TextDecoder to decode any text to unicode:

functionfetchAndDecode(file, encoding) {  
    var xhr = newXMLHttpRequest();  
    xhr.open('GET', file);  
    xhr.responseType = 'arraybuffer';  
    xhr.onload = function() {  
      if (this.status == 200) {  
        var dataView = newDataView(this.response);  
        var decoder = newTextDecoder(encoding);  
        var decodedString = decoder.decode(dataView);  
        console.info(decodedString);  
      } else {  
        console.error('Error while requesting', file, this);  
      }  
    };  
    xhr.send();  
  }

fetchAndDecode('gbkencoded.txt','gbk');
