Tim Allison commented on TIKA-4891:
-----------------------------------
I merged this for now. We'll see what the regression run for 4.1.0 shows on the
1.2 million files. We did run this on ~10k files during development.
[~tilman] , I _think_ I fixed the issue you mentioned. I couldn't reproduce the
encoding problem... is there a chance the encoding was altered when you
modified the tags?

> PDF/UA includes structural markup. We hacked out a standalone handler for
> this back in 1.x but haven't touched it in years.
>
> We should modernize our handling of structural tags and eventually consider
> turning that on by default. That decision will be based on evaluation on
> 1000s of PDFs. This is not a default switch to be taken lightly.
