it can handle inverted text. Though it should be able to get all
outlines, and you've helped him to achieve this.

Manuel,
I'm afraid just chaining command line tools won't help in this case.
I'm talking about programming.
And yes, I did solve many practical problems related to layout
analysis, and other fields of document image processing, and succeeded

Yep, quality is relatively poor so don't expect high accuracy from Tess.
Do you need every table cell's contents? Or getting numbers is just
enough and in a next step you can restore [predefined] item names?

Dear Sochenda,
I've checked the Unicode table range you've sent and now I see what the
problem is. I'd agree that in such algorithmic writing system (contrasted
with simpler positional systems like say Roman or Cyrillic) the stages of
pre-/post-processing are inevitable.
I'd suggest making
://code.google.com/p/tesseract-ocr/wiki/ReadMe). These are not quite
easy searchable documents but they contain all the info you might need.
