This property returns the recognition confidence for the specified character. This is the confidence of the main (selected) recognition variant. Confidence estimates the accuracy of a recognition variant. It should not be understood as a general recognition quality measure: the only safe use of confidence is for comparing recognition variants of the same character. The characters extracted from the source PDF file without recognition have confidence set to 55.
