Subject Re: [jira] Commented: (HARMONY-4196) [classlib][luni] InputStreamReader can't handle UnicodeBig encoding
Date Fri, 15 May 2009 03:40:16 GMT
Thanks Tim. That's the better way.

And ICU supports the "unicodebig" encoding. Try this:

Charset charset = CharsetICU.forNameICU("UnicodeBig");
System.out.println(charset);

It pass and return "UTF-16".
