MacOS X 10.9 - Link to the previous version (Apple) PDFKit framework

Question

Mac OS X 10.7.5 causes a sequential (and undocumented) change in behavior in the Quartz-PDFKit method

characterBoundsAtIndex

PDFPage class .

When you receive your text pdfPageas NSStringwith

text = [pdfPage string];

and get the unicode character in position idxusing

unichr = [text characterAtIndex: idx]; // (1)

You expect to get your borders (position and size) on the page with

bounds = [pdfPage characterBoundsAtIndex: idx]; // (2)

Using the same index value.

WRONG

After 10.7.5, there is no longer 1-1 correspondence with the index value (1) and the index value (2) , and worse, it is not provided for the transfer from the first to the last.
