Thanks!
Yes, I think that cmap claims to be identity, but isn't, which undermines our
strategy.
I tried replacing {{!toUnicodeCMap.hasUnicodeMappings()}} with
{{{}(!toUnicodeCMap.hasUnicodeMappings() &&
!toUnicodeCMap.hasCIDMappings()){}}}.
Now the file PDFBOX-4322-Empty-ToUnicode-reduced.pdf fails text extraction,
("Justin") is missing.

> Reporter: Oliver Schmidtmer
> Priority: Major

> The attached PDF uses Tahoma fonts.
> It seems the correct font is used, but it uses the wrong glyphs.
> For example the "6" from the screenshot is definitely from Tahoma Glyph 25 /
> CID 54, where it should be "S" Glyph 54 / CID 83.
> The "=" in screenshot is Glyph 32 CID 61 where "Z" Glyph 61 CID 90 should be
> used.
