--------------------------------------------------------------
Those are the "correct" bbox values for that font, i.e. that what's embedded in
the PDF. Given that the bbox is just metadata which doesn't affect rendering,
there's no incentive for them to be accurate - and even so, the bbox is the
upper bounds on the visual area of all glyphs for the font - so maybe they are
perfectly accurate when diacritics are taken into account. Note that when you
select the text in Acrobat, the bbox determines the height of the selection -
which matches the blue rectangles in PDFBox, so I suspect that they are correct.

> DrawPrintTextLocations is PrintTextLocations on steroids: after rendering an
> image, the bounds of the font sizes are drawn on it and the images are saved.
> This will allow to see whether a value shown by PrintTextLocations makes
> sense or not. The output as in PrintTextLocations will be kept. The classic
> PrintTextLocations will also be kept so that people don't write support
> questions.
