-/**
- * A <CODE>PdfString</CODE>-class is the PDF-equivalent of a JAVA-<CODE>String</CODE>-object.
- * <P>
- * A string is a sequence of characters delimited by parenthesis. If a string is too long
- * to be conveniently placed on a single line, it may be split across multiple lines by using
- * the backslash character (\) at the end of a line to indicate that the string continues
- * on the following line. Within a string, the backslash character is used as an escape to
- * specify unbalanced parenthesis, non-printing ASCII characters, and the backslash character
- * itself. Use of the \<I>ddd</I> escape sequence is the preferred way to represent characters
- * outside the printable ASCII character set.<BR>
- * This object is described in the 'Portable Document Format Reference Manual version 1.3'
- * section 4.4 (page 37-39).
- *
- * @see PdfObject
- * @see BadPdfFormatException
