Tilman Hausherr commented on PDFBOX-4884:
-----------------------------------------
It's not supported. I doubt it would be implemented. To do this, one would have
to analyze which glyphs are affected (might be possible, see
DrawPrintTextLocations.java example), and in a second step, find these in the
content stream, and delete / replace them individually while keeping the
position of non redacted glyphs. An additional problem is that a small font
subset could give away what was redacted.
