/**
 * Provides a simple bridge for writing the raw bytes of Unicode characters to
 * an output stream.
 * 
 * We write the "characters" as raw bytes to prevent Java from changing end of
 * line characters and fixing malformed byte sequences in the data. The data IS
 * THE DATA and it is not up to Java to decide when our data should be "fixed"
 * for us.
 * 

 * This class does nothing but provide some constructors that call the
 * OutputStreamWriter constructor with the appropriate values. No other methods
 * are overridden.
 * 
 * The first constructor takes an OutputStream and calls the superclass
 * constructor setting the encoding to UTF-16. The other constructors use the
 * parameter to construct a java.io.FileOutputStream object and then invoke the
 * first constructor with that.
