Tilman Hausherr commented on PDFBOX-5430:
-----------------------------------------
Yes but this is weird - this is an invoice. Why would anybody do this with
Adobe Illustrator?
My guess is that the invoice template was created with AI, and then the invoice
data was added by some buggy billing software.
This is the raw 4th content stream (formatting like this in the original):
{noformat}
BT
64 477 Td
[/F3 8 Tf
(Monatliche Kosten ) Tj
/F1 8 Tf
0 -11 Td
] TJ
ET
{noformat}
the correct content stream would have been
{noformat}
BT
64 477 Td
/F3 8 Tf
(Monatliche Kosten ) Tj
/F1 8 Tf
0 -11 Td
ET
{noformat}
