You must use a java.io.Reader derived class to handler Unicode.

Unicode characters are stored according to encodings:

• UTF-8, UTF-16, etc.

• US-ASCII

• ISO646-JP (Japanese)

Example:

InputStream is = ...;
Reader r = new InputStreamReader(is,"UTF-8");

// or look up the charset

Charset cs = Charset.forName("UTF-8");
Reader altr = new InputStreamReader(is,cs);
