The list of unique characters can later be used for identifying a whitelist to greatly improve the accuracy and performance of recognition.

Alternatives can be used to find out patterns in common recognition errors, such as misidentifying certain characters in a font used in an image, and to take corrective action, such as automatic substitution.
