I'm trying to get ToUnicodeMap generation working properly with GSUB but have hit problems
introduced by PDFBOX-4106. We'll have to resolve that before I can proceed here.

> Implemented proper rendering of Indian languages, which need extensive Glyph substitution.
The GSUB table has been read and used effectively to replace some compound words with their
respective Glyphs. All tests are passing. I have tested this for the Bengali font. Please
review these changes and let me know if it makes sense to incorporate these.
