You are right C++ is difficult because of the name mangling of function
symbols,
but good fortune I notice Tesseract has C bindings...
    https://github.com/tesseract-ocr/tesseract#for-developers
    https://github.com/tesseract-ocr/tesseract/blob/master/src/api/capi.h
so it looks like you are in the clear.

FFI will be more flexible.

I think its a great idea and actually Tesseract FFI is something I've
wanted to play with before but not had the time.
I'd be interested to hear how you go with it.
