public class PdfString
extends PdfObject

A PdfString-class is the PDF-equivalent of a JAVA-String-object.

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 \ddd escape sequence is the preferred way to represent characters outside the printable ASCII character set.
This object is described in the 'Portable Document Format Reference Manual version 1.3' section 4.4 (page 37-39).
