Tilman Hausherr commented on PDFBOX-4550:
-----------------------------------------
The attached file (from PDFBOX-3442) now fails text extraction because of
{code}
1 beginbfrange
<0000> <ffff> <0000>
endbfrange
{code}
One could modify the change from PDFBOX-4549, but that would bring more risks,
e.g. with the file [^pdnekz1gvl7.pdf].
> Poor performance with corrupt ToUnicode stream
