They can be. I don't know what is the state of the art in commercial OCR but artificial neural networks certainly can and have been applied to the problem.

Most often people use recurrent neural networks and specifically Hopfield networks. See for example:

In the real world you will have to deal with many problems such as skewed images for which you'd maybe use special preprocessing. See

The Anatomy of Bangla OCR System for Printed Texts Using Back Propagation Neural Network also tries to solve the problem of skewed images before running a neural network.

Feed-backpropagation neural networks could be used too: training feedforward neural network for OCR

Another type of feedforward networks called Convolutional neural network have also been applied to OCR:

There is a comparison of different OCR techniques and their performance on the MNIST database of handwritten digits:
