Single character 'I' recognition

[ElPasmo]

Hi!

I'm having trouble recognizing a capital 'I' . I've tried several configuration options that includes all the following:

tesseract I.jpg output -psm 10 -c load_system_dawg=0 -c load_freq_dawg=0 -c tessedit_write_images=1

As you can see, tessinput.tif shows that the I letter is not removed as noise.  I've also tried with a low 'a' and the same command succeded.

I'm trying to do a table OCR where some cells have only a letter so I need those capital 'I' to be succesfuly recognized.

Any thoughts?
