Additionally I've created a
pdf-testfile with Libre Office to investigate my assumption with special signs. Sorry for the german language in the document. The first file is the original Libre Office pdf.
The second one is generated by the M92. I marked the special signs in every line and tried to merge the pdf file (I've tried to create about 30 pdf files by merging). For the non marked lines it was not possible to merge the file. So you can see which characters provoke the bug. For the last block with the single characters I lost one's patience.
Original file:
pdf-Test-Dokument_Nr_2.pdf
File created by the M92:
pdf-Test-Dokument_Nr_2_2012-8-13_22-29-42.pdf
Another (small) bug is obvious: Sometimes the marked area does not coincide with the recorded text.
Perhaps it helps to solve the problem - my job as beta tester is done for today
