--------------------------------------------------------------
Ok, I took a look at this and the first attempt led me down the wrong path. The
issue is actually a bug in PDTrueTypeFont's encode method. There is a line
which looks up a GID via PDF character code but a Unicode character is passed
as the argument. Oops.
was (Author: jahewson):
The fonts used in the fields specify WinAnsiEncoding, however that encoding
does not contain the Euro symbol *[edit: actually it does - more research
needed]*, 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.
Note that 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 issue which I
mention in the previous paragraph.
