Tilman Hausherr commented on PDFBOX-283:
----------------------------------------
Done in rev 1608502 for the 1.8 branch and rev 1608506 for the trunk. Sorry for
the regression. The code made sense, I looked at the specification too, so I
committed it. Please test a snapshot version to be sure that all is OK now. If
possible, please submit a "minimal" code example that fails (e.g. with an
exception) with the bad code, and doesn't fail with the good code. I would then
add it as a test.

> 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())?
