Emmeran Seehuber commented on PDFBOX-5150:
------------------------------------------
I just tried your example default appearance string, but I then get this example
{code}
Caused by: java.io.IOException: Could not process default appearance string
'/Helv 0 Tf 0.0000 0.0000 0.0000 rg' for field 'null': Could not find font:
/Helv

{code}
It seems Helv can not be resolved as font. Shouldn't this be a builtin font,
which can always be found?
I've updated the branch open-dev-v1-pdfbox-3.0.0 with the changes to use Helv
as default if no font is given and also set the appearance before the value.
