Examples of java.nio.charset.Charset.encode()

java.nio.charset.Charset.encode()
Encodes the content of the give character buffer and outputs to a byte buffer that is to be returned.
The default action in case of encoding errors is CodingErrorAction.REPLACE.
@param buffer the character buffer containing the content to be encoded @return the result of the encoding
