Question about getEncoding method on different platforms

["Patrick Ellis" <Patrick dot Ellis at sas dot com>]

I have testcases that are failing across several platforms because the encoding value that is returned from the different platforms does not match the
8859_1 value that is being expected by the testcase. Example the value of ASCII is returned for Sun and Linux. 

Question: Should the mauve code be changed to reflect the correct values expected for each platform ?

getEncoding
public String <../../java/lang/String.html>  getEncoding()
	Return the name of the character encoding being used by this stream. 
	If the encoding has an historical name then that name is returned; otherwise the encoding's canonical name is returned. 
	If this instance was created with the OutputStreamWriter(OutputStream, String) <../../java/io/OutputStreamWriter.html>  constructor then the returned name, being unique for the encoding, may differ from the name passed to the constructor. This method may return null if the stream has been closed. 
Returns: 
	The historical name of this encoding, or possibly null if the stream has been closed
