I recently added the `lang` parameter with `-l` flag:
tesseract /tmp/ocr_snapshot.png stdout -l {query} 2>&1
It should allow you to run the command with `OCR fra` for french for example, but it should still work without any parameter. Tried just now and it works (Mac High Sierra & tesseract 3.05.01).
Possible solutions:
* add a way in the bash script to remove `-l` flag if `{query}` is undefined (don't know how to do this)
* downgrade to tesseract 3 as it seems to behave differently in 4
* remove this part in the bash script if you don't need it (see screenshot attached)
