Tessract (tessnet2 for .NET) - more than 2 decimal places

Question

I am strugling with a problem of reading data from a table. If a number has got up to 2 decimal places everything looks OK, when number has got 3 decimal places I am not getting decimal point, ie. (instead of getting 5.575 I am getting 5575).

! enter image description here

I have also tried tesseract 3.02 from https://github.com/charlesw/tesseract but I found this less reliable in reading data from source I want to read, that is why I am using old tessnet2.

I am using following white char list: ocr.SetVariable("tessedit_char_whitelist", "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ.,");

and language pack: english for version 2up.

Do you have any advices what can I modify in order to get more accurate values?

Thanks, Jack

Try bazaar or user-patterns in Tesseract 3.0x.
