Zero confidence for correct results.

[uğur]

1. I have an image ( tessinput.tif  , tesseract input result). If i call tesseract() with (-c whitelist='1234567890,;.') return correct result and high confidence. If I call tesseract with (whitelist='123456789' ) return the correct result with zero confidence. How to ignore some chars and prevent affecting confidence.

2. is it possible to get confidence per char.
