StringBuilder Encode Charset

Demonstrates the importance of the charset argument when encoding/decoding. Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    String s = "é é é";

    CkStringBuilder sb = new CkStringBuilder();

    sb.Append(s);
    sb.EntityDecode();

    //  The string now contains: "é é é"
    Log.i(TAG, sb.getAsString());

    //  If encoded to hex using the iso-8859-1 charset, 
    //  each é char is represented in 1 byte.
    //  Output: E920E920E9
    Log.i(TAG, sb.getEncoded("hex","iso-8859-1"));

    //  If encoded to hex using the utf-8 charset, 
    //  each é char is represented in 2 bytes.
    //  Output: C3A920C3A920C3A9
