Description
The PDF posted on the forms exhibits several glyph placement issues. I'll have to take a closer look but likely a corner case in the layout rules.

The issue turns out to be a very specific corner case for CID fonts. In short when when convert "\u0000" to a string we where returning an empty String in stead of a valid "0" cid. There are two caes "00" -> "0" or "0000" -> "0". Our HexStringObject.getLiteralStringBuffer() was incorrectly assuming that cid's couldn't be zero. I touched up the algorithm to not ignore a zero cid.

Corrected the getLiteralStringBuffer() method to correctly handle the zero'd CIDs.
