John Hewson commented on PDFBOX-2774:
-------------------------------------
The fonts used in the fields specify WinAnsiEncoding, however that encoding
does not contain the Euro symbol, which is why there is an exception. We could
do something like overwrite Encoding in the Font's dictionary but we should
probably look at how Acrobat handles this case first. This is a problem
specific to filling out form fields.
However, the two "small tests" do not reproduce the problem, they're calling
quite different methods which happen to result in the same exception because
PDTrueTypeFont.loadTTF creates a font which uses WinAnsiEncoding, while
PDType0Font.load supports full Unicode. There's no bugs in those examples and
this behaviour is expected and not relevant to the form-filling bug which I
mention in the previous paragraph.
