Andreas Lehmkühler resolved PDFBOX-534.
---------------------------------------

    Fix Version/s: 1.2.0
       Resolution: Fixed

I've found a solution for Ernestos pdf and committed it with version 944875.

There are 3 possible reasons for the described issues with pdfs created with tex/latex

- using an unknown glyphname
- using a hexadecimal (starting with a 'x' e.g. xF6) encoding instead of a glypname or a hexadecimal unicode
- using a decimal (starting with an 'a' e.g. a128) encoding instead of a glypname or a hexadecimal unicode

I've created an addtional glyph-mapping file to adress the unknown glyphnames and extended Encoding.getCharacter() to handle the hexadecimal and the decimal encodings

Thomas pdf uses Type3 fonts with Glyphs which can'be extracted even with the Acrobat Reader.

> I'm getting an unexpected behavior parsing a pdf file.
> I'm trying to get the clean body text of some file, and I get a lot of aXX strings. Where each X is a number. It appear be the char code of the real character, I don't know really.
> My code is too simple:
>           String[] args = {"/home/ernesto/tesis/documento/kvfs.pdf"};
>           ExtractText.main(args);
> I used the PDFBox 0.8.0-incubator version. Builded on 20/9/2009. 
> The output I get is:
