/**
* {@link InputStream} implementation that reads a character stream from a {@link Reader} and transforms it to a byte
* stream using a specified charset encoding. The stream is transformed using a {@link CharsetEncoder} object,
* guaranteeing that all charset encodings supported by the JRE are handled correctly. In particular for charsets such
* as UTF-16, the implementation ensures that one and only one byte order marker is produced.
* <p>
* Since in general it is not possible to predict the number of characters to be read from the {@link Reader} to satisfy
* a read request on the {@link ReaderInputStream}, all reads from the {@link Reader} are buffered. There is therefore
* no well defined correlation between the current position of the {@link Reader} and that of the
* {@link ReaderInputStream}. This also implies that in general there is no need to wrap the underlying {@link Reader}
* in a {@link java.io.BufferedReader}.
* </p>
* <p>
* {@link ReaderInputStream} implements the inverse transformation of {@link java.io.InputStreamReader}; in the
* following example, reading from {@code in2} would return the same byte sequence as reading from {@code in} (provided
* that the initial byte sequence is legal with respect to the charset encoding):
* </p>
*
* <pre>
* InputStream inputStream = ...
* Charset cs = ...
* InputStreamReader reader = new InputStreamReader(inputStream, cs);
* ReaderInputStream in2 = new ReaderInputStream(reader, cs);
* </pre>
* <p>
* {@link ReaderInputStream} implements the same transformation as {@link java.io.OutputStreamWriter}, except that the
* control flow is reversed: both classes transform a character stream into a byte stream, but
* {@link java.io.OutputStreamWriter} pushes data to the underlying stream, while {@link ReaderInputStream} pulls it
* from the underlying stream.
* </p>
* <p>
* Note that while there are use cases where there is no alternative to using this class, very often the need to use
* this class is an indication of a flaw in the design of the code. This class is typically used in situations where an
* existing API only accepts an {@link InputStream}, but where the most natural way to produce the data is as a
* character stream, i.e. by providing a {@link Reader} instance. An example of a situation where this problem may
* appear is when implementing the {@code javax.activation.DataSource} interface from the Java Activation Framework.
* </p>
* <p>
* Given the fact that the {@link Reader} class doesn't provide any way to predict whether the next read operation will
* block or not, it is not possible to provide a meaningful implementation of the {@link InputStream#available()}
* method. A call to this method will always return 0. Also, this class doesn't support {@link InputStream#mark(int)}.
* </p>
* <p>
* Instances of {@link ReaderInputStream} are not thread safe.
