Description

Hi encountered a rare exception with an empty TTF subset:

==> [1] caused by java.lang.IllegalStateException: subset is empty
1.: org.apache.fontbox.ttf.TTFSubsetter.writeToStream(TTFSubsetter.java:921)
2.: org.apache.pdfbox.pdmodel.font.TrueTypeEmbedder.subset(TrueTypeEmbedder.java:304)
3.: org.apache.pdfbox.pdmodel.font.PDType0Font.subset(PDType0Font.java:162)
4.: org.apache.pdfbox.pdmodel.PDDocument.save(PDDocument.java:1102)
5.: com.helger.pdflayout.PageLayoutPDF.renderTo(PageLayoutPDF.java:276)

Unfortunately I don't know yet what was causing the problem, but I will provide you with more details on Monday (if necessary).

If there is nothing to subset - I think the call should simply be ignored???
Or maybe this is a problem because of the "uni" name bug (in 2.0.0-RC2) I reopened lately?
