The rendering engine is a port of Xpdf.

PocketXpdf has been tested on an ASUS MyPal running Windows Mobile 2003 and on a Dell Axim X51v running Windows Mobile 5.0. It has not been tested on earlier versions, so it cannot be guaranteed that it will work on these systems.

Known bugs and limitations:
- Zooming in too far will make the program run out of memory and cancel the zooming.
- Some PDF files may crash the program. Please report!
- No support for non-western character encodings.
- No support for PocketPC 2002 or older Smartphone editions.
