Tim Allison updated TIKA-2846:
------------------------------
Description:
As part of TIKA-2749, it would be useful to gather stats on characters that did
not have a unicode mapping. Users could use this information now to determine
which pages might benefit from OCR.
I propose an array of floats/doubles, with one entry per page. The
float/double would be (# of characters without unicode mapping/total # of
characters) per page.
We might also want an int array for total number of characters per page.
Many thanks to [~tilman] for the guidance on how to gather this info easily.
