fill form using japanese font #779
Description
I have set up a text field with a Japanese font. When I try to insert text here, the font is recognized, but I get the error pdfcpu: corrupt fontDic.
After some investigation, the code below cause this error.
pdfcpu/pkg/pdfcpu/font/fontDict.go
Lines 117 to 120 in b89d7b1
I'm not familiar with PDF specifications, but it seems like the problem is accessing 7 instead of 8.
Maybe there is a problem if the subsetted font for the embedded text and the font set on the form are the same?

By the way,
I produce the PDF file with forms with ONLYOFFICE Desktop Editors.
The file contain DA parameter with the value like 0.000000 0.000000 0.000000 rg \057F2 20.000000 Tf, so I have to patch parsing code to convert \057 to \.
