UN/EDIFACT Syntax Level A Encoding/Decoding

Demonstrates the new "eda" encoding that can be used throughout Chilkat starting in v9.5.0.65. Android™

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

  // Called when the activity is first created.

    // UN/EDIFACT syntax level A character set.
    sb.Encode("eda","utf-8");

    // EDA Output should be: BTME027FCF6CFARFI94JT6.)F(14KJ2U

    // Decode back to the original string.
