Document Text


Adobe PDF documents were originally designed to provide a way to graphically render and print a document on a wide variety of operating systems and printers in a consistent way.
To do this the basis of the PDF document is graphical presentation of all the content, including text content.
As PDF format was enhanced the ability to extract the graphical characters as text content was added.
This can be used by search functions and provides the capability to cut and paste content into other applications.
This can also be used by assistive technologies to provide an alternative rendering of the text content.

It is important that the characters used to render the content can be converted to text for alternative rendering.
All the text content therefore must be represented as a font and that font information is available to convert the characters to unicode characters.
