OSD mode (--psm 0) always returns dummy results when language (-l eng, -l pol, etc.) is specified

[Twixes]

Environment

• Tesseract Version: 4.1.1 and 5.0.0-alpha-635-g90405
• Platform: macOS 10.15.3 (tested with v4) and Ubuntu 18.04 (tested with v4 and v5)

Current Behavior:

Invocations with options --psm 0 -l eng always return the same dummy results for all valid images:

Orientation in degrees: 0
Rotate: 0
Orientation confidence: 0.00
Script: Latin
Script confidence: 2.00

Expected Behavior:

Results should contain actual Orientation degrees, Rotate and Orientation confidence values.

Solution: do not use language specification when you for osd.

I thought it should be working with language specification? #1926 (comment)

It looks like a duplicate of #2062.

You need to:

1. Download eng.traineddata from the tessdata repo,
2. Create new tessdata directory somewhere.
3. Add --tessdata-dir /path/to/your/tessdata to the the tesseract command.
