John Hewson commented on PDFBOX-3056:
-------------------------------------
Oh, there are two parts of PDFTextStreamEngine#onGlyph which you might want to
keep (but both are non-standard w.r.t PDF so we don't expose them in
PDFStreamEngine). The first is the additional.txt glyph list (which you're free
to update), the second is the Acrobat-like fallback behaviour for Unicode
following the "when there is no Unicode mapping available [...]" comment.

> I'd like to experiment with writing my own text extractor that works better
> for my use case than PDFTextStripper does. Hopefully I can port some of the
> improvements to PDFTextStripper if I get something working well. I'd really
> like PDFTextStreamEngine and its constructor to have increased visibility as
> I believe that it's pretty reasonable for people to be able write their own
> PDFTextStrippers without having to reimplement showGlyph.
