Lapo Luchini commented on PDFBOX-5411:
--------------------------------------
Yes, that makes sense. It is not an "easy" case, just a "IMHO somewhat
solvable" one.
Example given: I would prefer to have text separation for the first example and
"nothing" (but single letters) for a case like this:
!image-2022-04-15-09-26-20-917.png!
what I mean is: it's not a change that would only bring good results, it would
potentially break existing good ones, but maybe the improvement in the firsts
is better than the worsening of the latter.
And maybe a "text size difference of max ±20%" would be a good heuristic to
have both (I wonder).

> When two texts are partially overlapping {{PDFTextStripper}} seems to return

> currently this is the first parameter of PDFTextStripper.writeString(String

> I would of course hope for two calls:
