Note by @amitdo. The original title was: Inconsistency Between --oem and -c "tessedit_ocr_engine_mode"

Current Behavior

As far as I can tell, these two options should be identical, however the attached image produces different output. With --oem it says 11, with the config var it says 1. I should add that with any --oem value other than 0, it returns '1' not '11'.

Full command:

tesseract -l eng --oem 0 --psm 7  -c "tessedit_char_whitelist=0123456789"  ramdisk/test_0.png  -
tesseract -l eng --psm 7  -c "tessedit_char_whitelist=0123456789" -c "tessedit_ocr_engine_mode=0" ramdisk/test_0.png  -

Expected Behavior

Both commands should return the same result, ideally 11.

Suggested Fix

They should either return the same information or the docs should be updated to clarify the difference.
