I understand what you said! Well, yes I used the unsorted mode for the picture.
So, I understood that the sorted mode failed for the two cases. It probably
sorts glyphs according to their distance to the top of the page.

> Dear Apache contributors,
> I am a (y) user of pdfbox mainly for the purpose of text extraction. The word
> ordering is not correct for some cases and the line detection may fail too.
> Attachments:
> * 1st page: the first letter D is not written before "uis sit amet..." but
> at the end of the page ;
> * 2nd page: the sentence "scolaire ferry" is just before "réouverture du
> musée" which is wrong because it's not on the same column ;
> To manage these cases would be more than welcome :D A.
