OCR a test image with you app, store result to text file. Than OCR the same image with tesseract executable (output should be in text file by default) and compare results. If output from tesseract executable is OK, but from your app is wrong (e.g. there are only ascii letters) => you have problem within you app (e.g. it does not handle unicode string correctly).
