How to convert Big5 encoded text into UTF8 in Dart?

[何宗憲]

Hi All,

    I was trying to convert a web-based context, encoded in big5, into UTF8. However, I do not see dart:convert supports Big5 encoding yet. Could anyone suggest me an alternative?

    Also, I currently use iconv in javascript for this purpose but hopes to integrate all my functions into dart. I tried 'dart:js' but it has problem recognizing keyword 'require'. Please enlighten me up. Thanks! Here is my code in dart:

main.dart:

var js1 = new JsObject(context['jsFileStreamer'], ["../insurance.b5"]);
js1.callMethod('receive', []);

A snippet of the jsFileStreamer is: 

var jsFileStreamer = function jsFileStreamer(FileName){

    this.fileName = FileName;

    // this function is to produce a file in csv format

    this.receive = function(outName){
      var iconv = require('iconv-lite');
  };
};

There seems no package available yet which provides Big5 support.

When you use 'require' in your JavaScript code you need to load a JavaScript library that provides this function.

This is not an issue of 'dart:js'. See for example http://stackoverflow.com/questions/9901082/what-is-this-javascript-require

Hi,

About the encoding problem see this similar question http://stackoverflow.com/a/26967535/634863

About the dart;js usage, it looks good. "require" is called on the js side, so you have to ensure this function is defined (by including http://requirejs.org/ ?).

Cheers,

Alexandre

Do you consider porting it to dart version?
