------------------------------------------------------------------
Attached file no longer extracts text, ToUnicode stream is at
{{Root/Pages/Kids/[0]/Resources/Font/F3/ToUnicode}}, and it has
{code}
1 beginbfrange
<0000> <FFFF> <0000>
endbfrange
{code}
So that's a range > 255 and thus it is ignored.

> A confidential file with lots of corrupt streams has ToUnicode stream with
> corrupt contents in the beginbfrange segment where start and end have
> different lengths. This leads to poor performance. Such entries can be
> skipped.
