---------------------------------
Summary: PDAcroForm.refreshAppearances() does not respect updated
fonts
Key: PDFBOX-3597
URL: https://issues.apache.org/jira/browse/PDFBOX-3597
Project: PDFBox
Issue Type: Bug
Components: PDModel
Affects Versions: 2.0.3
Reporter: Matt Wise
I have attached example files in the External issue URL link.
I am trying to embed a subset of a font into my pdf after populating the
fields. If I don't run refreshAppearances() the values will be put into the
fields, but will only be visible when the field is selected (likely another
bug).
To work around this, I am trying to set the default appearance on the fields
manually to reflect the embedded font. If I embed the whole font, it works as
expected, however when I try to embed a subset of the font it fails:
Exception in thread "main" java.lang.IllegalArgumentException: No glyph for
U+540D in font AAWTXC+ArialUnicodeMS

at test_pdfbox.TestPDFBox.main(TestPDFBox.java:45)
It would appear that after I call form.setDefaultResources with the updated
font, refreshAppearances is still trying to use the old font as the appearance,
although I may be wrong.
Expected:
appearances are updated, subset of font is embedded.
