Class CharacterConverter

java.lang.Object

java.nio.charset.Charset

totalcross.sys.AbstractCharacterConverter

totalcross.sys.CharacterConverter

All Implemented Interfaces:

java.lang.Comparable<java.nio.charset.Charset>

Direct Known Subclasses:

CompressedByteArrayStream.DirectCharConverter

public class CharacterConverter
extends AbstractCharacterConverter

This class is used to correctly handle international character convertions. The default character scheme converter is the 8859-1. If you want to use a different one, you must extend this class, implementing the bytes2chars and chars2bytes methods, and then assign the public member of totalcross.sys.Convert.charConverter to use your class instead of this default one. You can also use the method Convert.setDefaultConverter to change it, passing, as parameter, the prefix of your CharacterConverter class. For example, if you created a class named Iso88592CharacterConverter, call Convert.setDefaultConverter("Iso88592");

To find out which sun.io.CharacterEncoder you're using, do:

System.out.println(""+sun.io.ByteToCharConverter.getDefault());
