com.itextpdf.text.pdf.PdfName
PdfName is an object that can be used as a name in a PDF-file.
A name, like a string, is a sequence of characters. It must begin with a slash followed by a sequence of ASCII characters in the range 32 through 136 except %, (, ), [, ], <, >, {, }, / and #. Any character except 0x00 may be included in a name by writing its two character hex code, preceded by #. The maximum number of characters in a name is 127.
This object is described in the 'Portable Document Format Reference Manual version 1.7' section 3.2.4 (page 56-58).
