Wraps a String as an InputStream. Note that data will be lost for characters not in ISO Latin 1, as a simple
char->byte mapping is assumed.
Author:

Deprecated:
As of version 1.5.2 this class should no longer be used because it does not properly handle character encoding. Instead, wrap the output from String.getBytes(String) into a ByteArrayInputStream./**
