This happens when I have a Japanese embedded font.
{quote}
The font isn't embedded in the acroform fields. It is embedded for the page,
which is not the same, it should have been embedded in /AcroForm/DR or in the
field/DR. This is likely a bug in Excel, from which this was exported.
Of course it is still a PDFBox bug. And it gets worse: I can't reproduce it
because I don't have the "HiraKakuPro-W3" font on my local system, and I get a
second, different bug with the substituted font:
{code}
WARN [main] org.apache.pdfbox.pdmodel.font.PDCIDFontType0:146 - Using fallback
ArialUnicodeMS for CID-keyed font HiraKakuPro-W3

This is because encode of a CIDFontType0 as descendent font isn't implemented
yet :-(
{code}
@Override
public byte[] encode(int unicode)
{
// todo: we can use a known character collection CMap for a CIDFont
// and an Encoding for Type 1-equivalent
throw new throw new UnsupportedOperationException();
}
{code}
So this won't be fixed soon. Please try a different font and see if it works.
If possible, attach an excel file that uses a more common font, maybe this
could help a little bit.
