I actually asked that question, and don't have an answer yet.  Are there 
any listed terms of use or such?

<aside>
Lets not distinguish the PPMC that way - no need to place any special 
empahsis there.

Paulex Yang commented on HARMONY-156:
-------------------------------------

All the spec about Charset historical name is:
" Some charsets have an historical name that is defined for 
compatibility with previous versions of the Java platform. A 
charset's historical name is either its canonical name or one of its 
aliases."

From this paragraph, I personally think the historical name is 
specific to RI without any public standard:(,  so the only way to be 
compatible with RI is write testcases to get all historical names of 
RI supported Charsets, and store them in an map.

I can provide the patch of tests(to get all historical name) and the 
mapping implementation, but before that, I hope I can get some better 
idea from the mailing list to avoid this ugly solution:-\.

 

InputStreamReader.getEncoding() and OutputStreamWriter.getEncoding() 
should return a historical charset name.

        Key: HARMONY-156
        URL: http://issues.apache.org/jira/browse/HARMONY-156
    Project: Harmony
       Type: Bug
 Components: Classlib
   Reporter: Dmitry M. Kononov
   Priority: Minor
  

 

InputStreamReader.getEncoding() and OutputStreamWriter.getEncoding() 
return canonical names on the given charsets instead of historical 
ones. For example,
   new OutputStreamWriter(new ByteArrayOutputStream(), 
"UTF-16BE").getEncoding()
has to return the "UnicodeBigUnmarked" string as a historical name. 
But it returns "UTF-16BE", that is a canonical name.
The java spec reads the historical names as the charset names 
defined for compatibility with previous versions of the Java platform.
