You are right C++ is difficult because of the name mangling of function
but good fortune I notice Tesseract has C bindings...
so it looks like you are in the clear.

Or should I forget the API and use OSProcess to start the tesseract

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.
