Detailed Description

A string that can be written to a PDF document. If it contains binary data it is automatically converted into a hex string, otherwise a normal PDF string is written to the document.

PdfStrings representing text are either in PDFDocEncoding (ISO Latin1) encoded or UTF-16BE encoded.

PoDoFo contains methods to convert between these encodings. For convinience conversion to UTF-8 is possible to. Please not that strings are always stored as UTF-16BE or ISO Latin1 (PdfDocEncoding) in the PDF file.

UTF-16BE strings have to start with the byts 0xFE 0xFF to be recognized by PoDoFo as unicode strings.

PdfStrings is an implicitly shared class. As a reason it is very fast to copy PdfString objects.

The internal string buffer is guaranteed to be always terminated by 2 zeros.
