Sure! My current experiement is to add the information about character and word spacing to Chunk, copy the information to PdfChunk and then using it to calculate the correct width in BidiLine.processLine(). The biggest hurdle is right now to combine it with the justify alignment in PdfDocument.writeLineToContent(). If this works then you have the instrument to control windows and it is possible to add an automatic algorithm.
