> Key: PDFBOX-3144
> URL: https://issues.apache.org/jira/browse/PDFBOX-3144
> Project: PDFBox
> Issue Type: Bug
> Components: FontBox
> Affects Versions: 2.0.0

> Reporter: Philip Helger

> An NPE happens in "public void TTFSubsetter.add(int unicode)" because the "unicodeCmap" member is null.
> This might be, because the passed "ttf" member is based on a "MemoryTTFDataStream" and has only 38 glyphs (so it might already be a subset). The available tables of the TTF are only: [fpgm, head, cvt , glyf, loca, gasp, hmtx, prep, hhea, maxp]
> The variables of the underyling font are:
> {code}
> this PDType0Font (id=58)
> afmStandard14 null
> avgFontWidth 0.0
> cMap CMap -> Identity-H
> cMapUCS2 null
> descendantFont PDCIDFontType2 (id=155)
