Add capability for font subsets to put latin glyphs in a separate subset
This is required to allow PDF/PS output to use "(this is ascii)" style
strings that can be post processed by applications like psfrag. It
will also reduce the file size when a large amount of latin text is
used due to the 8-bit encoding instead of the 16-bit used for CID
fonts.
The winansi encoding (CP1252) is used for the latin subset as this is
a standard PDF encoding. Some PDF readers have buggy support for non
standard PDF 8-bit encodings.
