org.loboevolution.pdfview.PDFDocCharsetEncoder

public class PDFDocCharsetEncoder
extends CharsetEncoder

Encodes into a PDFDocEncoding representation. Note that only 256 characters (if that) are represented in the PDFDocEncoding, so users should be prepared to deal with unmappable character exceptions.
