You're using Tesseract to try to crack captchas? Interesting... There are other projects around that are focused on this; I don't know how they work, but it might be worth you checking them out as well. There are two obvious issues here. First is that the text has noise around it, which is hampering Tesseract's recognition. If possible you should try to pre-process it to remove as much noise as possible. Second is that it looks likely that you only expect to see ASCII characters. If that is the case, use the whitelist function to ensure that characters like euro and a-circumflex are never considered. It is explained in this FAQ entry: http://code.google.com/p/tesseract-ocr/wiki/FAQ#How_do_I_recognize_only_digits?
