# PdfCMapTable

## Content

# Class: PdfCMapTable

Represents a CMap table.

A CMap specifies the mapping from character codes to character selectors,
it is used to extract Unicode text from PDF documents.
In most cases CMaps are fully embedded into the PDF document.
But in rare cases a CMap in a PDF is specified by a PDF name object,
where this name identifies a predefined CMap that should be known to the PDF processor.
