/**
* This class reads characters from a byte input stream. The characters
* read are converted from bytes in the underlying stream by a
* decoding layer. The decoding layer transforms bytes to chars according
* to an encoding standard. There are many available encodings to choose
* from. The desired encoding can either be specified by name, or if no
* encoding is selected, the system default encoding will be used. The
* system default encoding name is determined from the system property
* <code>file.encoding</code>. The only encodings that are guaranteed to
* be availalbe are "8859_1" (the Latin-1 character set) and "UTF8".
* Unforunately, Java does not provide a mechanism for listing the
* ecodings that are supported in a given implementation.
* <p>
* Here is a list of standard encoding names that may be available:
* <p>
* <ul>
* <li>8859_1 (ISO-8859-1/Latin-1)
* <li>8859_2 (ISO-8859-2/Latin-2)
* <li>8859_3 (ISO-8859-3/Latin-3)
* <li>8859_4 (ISO-8859-4/Latin-4)
* <li>8859_5 (ISO-8859-5/Latin-5)
* <li>8859_6 (ISO-8859-6/Latin-6)
* <li>8859_7 (ISO-8859-7/Latin-7)
* <li>8859_8 (ISO-8859-8/Latin-8)
* <li>8859_9 (ISO-8859-9/Latin-9)
* <li>ASCII (7-bit ASCII)
* <li>UTF8 (UCS Transformation Format-8)
* <li>More later
* </ul>
* <p>
* It is recommended that applications do not use
* <code>InputStreamReader</code>'s
* directly. Rather, for efficiency purposes, an object of this class
* should be wrapped by a <code>BufferedReader</code>.
* <p>
* Due to a deficiency the Java class library design, there is no standard
* way for an application to install its own byte-character encoding.
