the sample is a junit test written in kotlin

> POCIDFontType2 (Wingdings) encode throws a NullPointerException
> ---------------------------------------------------------------
>
> Key: PDFBOX-5402
> URL: https://issues.apache.org/jira/browse/PDFBOX-5402
> Project: PDFBox
> Issue Type: Bug
> Components: FontBox
> Affects Versions: 2.0.21, 2.0.22, 2.0.23, 2.0.24, 2.0.25
> Environment: PDFBox 2.0.25 used via a gradle plugin (has been tested
> as far back as PDFBox 2.0.21)
> Reporter: Matthew Bayer
> Priority: Major
> Attachments: Wingdings.pdf
>
>
> Problem;
> * It is known that wingdings based fonts do not support encoding from
> https://issues.apache.org/jira/browse/PDFBOX-4714. However it is unexpected
> that a call to encode on a wingdings POCIDFontType2 returns a
> NullPointerException.
> Notes:
> * The issue seems to lie within PDFont POCIDFontType2
> * The POCIDFontType2 encode function is only known to throw IOException or
> UnsupportedOperationException(s)
> * Please see the attached test file with the font in question that causes
> the NullPointerException to be thrown
> * Stacktrace:
> {code:java}
> java.lang.NullPointerException
> at
> org.apache.pdfbox.pdmodel.font.PDCIDFontType2.encode(PDCIDFontType2.java:359)
> at
> org.apache.pdfbox.pdmodel.font.PDType0Font.encode(PDType0Font.java:424)
> at org.apache.pdfbox.pdmodel.font.PDFont.encode(PDFont.java:333)
> {code}
