Tilman Hausherr commented on PDFBOX-3076:
-----------------------------------------
[~jhirsh] how important is this for your application? Can you use some default
value? (e.g. the width?) While Adobe Reader is able to mark the glyphs, PDF.JS
does also have a problem with your file, they take a huge height when marking.

In theory, it could be possible to get the height from the charprocs d1
operator parameters, i.e. go through all of them and then get the highest value
from all.
