question: public int read ( ) throws IOException { int b0 = fInputStream . read ( ) ; if ( b0 > 0x80 ) { throw new IOException ( Localizer . getMessage ( "jsp.error.xml.invalidASCII" , Integer . toString ( b0 ) ) ) ; } return b0 ; }
target:  Read a single character.  This method will block until a character is available, an I/O error occurs, or the end of the stream is reached. <p> Subclasses that intend to support efficient single-character input should override this method.
