             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 org.apache.pdfbox.pdmodel.interactive.form.PDAcroForm.refreshAppearances(PDAcroForm.java:318)
	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.
