> When trying to call stripper.getText on the PDF file
> http://www.edi-energy.de/files2/EDI@Energy%20UTILMD%205.1_20130401.pdf,
> PDFBox 1.8.2 emits the following warning:
> 08:48:20,222 WARN PDFStreamEngine:567 - java.io.IOException: Error: Could

> Interestingly, PDFBox 2.0 emits a different warning that calls out the
> problem more precisely:

> extractToUnicodeEncoding
> SEVERE: Error: Could not load embedded ToUnicode CMap

> We could trace the problem down to reading pages that contain special
> characters (e.g. €). In the referenced PDF document, pages that do not
> contain special characters (e.g. €) do not cause the above mentioned warning.
> The text parts in the document that cause the warning do not get parsed
> correctly. The parse result contains byte rubbish.
> Adobe reader displays the entire document correctly.
> The following snippet should serve as a repro:
> package com.regiocom.bpo.mig;
> import java.io.File;
> import java.io.FileInputStream;
> import java.io.FileNotFoundException;
> import java.io.IOException;
> import java.util.List;

> public class Repro {
>
> public Repro() {
>
> try {
> stripper = new PDFTextStripper();
> } catch (IOException e) {
> e.printStackTrace();
> }
> }
> // use this PDF as input:
