charset}. The charset that it uses may be specified by name or may be given explicitly, or the platform's default charset may be accepted. Each invocation of a write() method causes the encoding converter to be invoked on the given character(s). The resulting bytes are accumulated in a buffer before being written to the underlying output stream. The size of this buffer may be specified, but by default it is large enough for most purposes. Note that the characters passed to the write() methods are not buffered.
For top efficiency, consider wrapping an OutputStreamWriter within a BufferedWriter so as to avoid frequent converter invocations. For example:
Writer out = new BufferedWriter(new OutputStreamWriter(System.out));
A surrogate pair is a character represented by a sequence of two char values: A high surrogate in the range '\uD800' to '\uDBFF' followed by a low surrogate in the range '\uDC00' to '\uDFFF'.
A malformed surrogate element is a high surrogate that is not followed by a low surrogate or a low surrogate that is not preceded by a high surrogate.
This class always replaces malformed surrogate elements and unmappable character sequences with the charset's default substitution sequence. The {@linkplain java.nio.charset.CharsetEncoder} class should be used when morecontrol over the encoding process is required. @see BufferedWriter @see OutputStream @see java.nio.charset.Charset @author Mark Reinhold @since JDK1.1
