[jira] [Updated] (PDFBOX-3461) Improve handling of control characters when setting AcroForm field values

["Maruan Sahyoun (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PDFBOX-3461?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Maruan Sahyoun updated PDFBOX-3461:
-----------------------------------
    Attachment: ControlCharacters.pdf

[^ControlCharacters.pdf] sample of fields filled manually and via JavaScript using Adobe Acrobat for NUL, CR, LF, TAB, CRLF, LFCR as well as U+2028 (line break) and U+2029 (paragraph break).

Will use it as the basis for implementing similar handling in PDFBox as well as a unit test.

> When filling AcroForm fields the text supplied to {{setValue}} might contain control characters such as {{\n}} {{\r}}, {{\t}} and others which leads to an {{ java.lang.IllegalArgumentException}} for most fonts as there is no glyph to represent these.
> We could enhance the processing of the string provided to provide proper replacements similar to how Adobe Acrobat handles that.
