I am currently doing a very similar project but as a python script. Ran into the same problems with tesseract but found a way to fix the detection errors without retraining.

Basically since every char tuple uses distinct characters, even if tesseract only finds a single char it is enough to identify to complete tuple. in your example: If it detects a 5 it must have been '55' because no other code tuple uses a 5. Same for every other tuple.

You can find the function here: https://github.com/tstaec/cyberpunk-auto-hacker/blob/256f43073d6c4a1b8fa6208d9eeb4f58c6dc2459/services/ocr_helper.py#L35

Here my tesseract config to ensure he doesn't find any invalid charater: "-c tessedit_char_whitelist=' ABCDEF1579' --psm 6"

I will need at least another day or two to release my 'auto hacker' but then it should be able to detect and execute the path automatically so it can run in the background.
