UTF-8/16/32 based encoding and decoding (Experimental)
This is an experimental class which implements partial support UTF-8, UTF-16 and UTF-32 encoding.
At this stage it only provides the ability to read CMap encodings with
UTF32 in the name.
This class is based on PDF::Font::Loader::Enc::CMap and has all its methods available, except for
make-to-unicode-cmap, which dies with a X::NYI error.
