[jira] [Commented] (PDFBOX-283) Character encoding/appearance issues when filling forms

    [ https://issues.apache.org/jira/browse/PDFBOX-283?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14174068#comment-14174068 ] 

Maruan Sahyoun commented on PDFBOX-283:
---------------------------------------

There are still issues with the appearance generation but this is now being dealt with in PDFBOX-2333. Linking that and keeping it open to ensure we use the information provided as a testbed.

This also relates to PDFBOX-922 to resolve the encoding issue. So linking that too.

> When filling a text field with non-ASCII characters such as in my surname "SkyttÃ¤" 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 "Ã¤" 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 "Ã¤" 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())?
