Bernd Köster commented on PDFBOX-283:
-------------------------------------

I did some work on the PDAppearace. You need to use the code above on every substring in the
convertMulitline method.

> When filling a text field with non-ASCII characters such as in my surname "Skyttä"
and saving the document in a UTF-8 environment, something goes wrong with the appearance of
the text.
> The value itself seems to be stored correctly, but when opening the doc, the appearance
of "ä" is not that, but rather something which happens when UTF-8 is mistakenly treated
as ISO-8859-1 (two garbage characters).
> PDAppearance uses the platform default encoding in quite a few places which apparently
has potential to mess things up.  In particular, insertGeneratedAppearance() generates a PrintWriter
from an OutputStream without specifying the encoding.  In fact, if I hack that to use ISO-8859-1,
the appearance of my "ä" case is correct, but that won't obviously work with anything else
than chars that are valid ISO-8859-1.
> In which char encoding should the value be written to the appearance stream (at end of
insertGeneratedAppearance())?
