There are two problems. The first is that buildOS2Table() doesn't work properly
when there is no element in the uniToGID table so we could throw an
IllegalStateException. The second problem is that buildOS2Table() won't work
properly if there is only one element in the table. This is because of this
code segment:
{code}
Iterator<Entry<Integer, Integer>> it = uniToGID.entrySet().iterator();
it.next();
Entry<Integer, Integer> first = it.next();
{code}
The original code by [[email protected]]
http://svn.clazzes.org/svn/sketch/trunk/pdf/pdf-entities/src/main/java/org/clazzes/sketch/pdf/entities/impl/TTFSubFont.java
expects a .notdef there and it is added. Our code doesn't do this anymore, this
was partially lost in PDFBOX-2565 / [ https://svn.apache.org/r1645796 ] where
{{addCharCode(0);}} was replaced by {{glyphIds.add(0);}}
