The problematic number is the number sign, but as UTF8. But the PDF
specification mentions "It shall use the beginbfchar, endbfchar, beginbfrange,
and endbfrange operators to define the mapping from character codes to Unicode
character sequences expressed in UTF-16BE encoding."
However Adobe Reader is able to extract it.

> The problems are somehow related to the /ToUnicode stream at
> {{Root/Pages/Kids/[0]/Resources/Font/F3/ToUnicode}}. This is a different bug
> than PDFBOX-5960 and not the problem that is in PDF.js 19527. I played around
> a bit supporting 3 byte codes (memo for me: version before 21.2 12:20) but
> it's still the same exception.
