** Description changed:

  ******* this report is a summary of known problems
  
  The text recognition feature (OCR - Region.text()) together with the
  possibility to find text in an image is still experimental and under
  developement.
  
  This are currently reported bugs:
  bug 777660: text recognition errors with some fonts
+ bug 783082: [request] want font parameters for text recognition
  bug 735434: Text extraction from Images fails in some cases on colored backgrounds
  bug 695616: Inconsistency in text recognition and matching, especially with integers-as-text!
  bug 695650: find(text).text() does not return same text
  bug 701005: text() always returns text with trailing x'200A20'
  bug 701012: text() does not return all intervening blanks, add's others
  
  Other experienced oddities
  -- there are problems with text, that is not in english language
  -- very small and very large fonts may not work
  -- multiline text makes problems
  -- intervening/preceding/trailing grafics and symbols are tried to be interpreted as text
  
  Tip when using Region.text():
  Currently you get the best results, when the region represents only one line of text and only contains text (no graphics/symbols) in english language. If you can influence it: make the text as large as possible.
  
  -- additional information:
  Internally the tesseract OCR engine (http://code.google.com/p/tesseract-ocr/) is used.
  So their restrictions apply (e.g. minimum size of font, ...).
  Information can be found on their Wiki.
