Palash Ray commented on PDFBOX-4189:
------------------------------------
Hi Tilman,
I have opened a new PR:
[https://github.com/apache/pdfbox/pull/47]
This change set contains some refinement to the code so that GSUB can be
supported for any languages with ease. As mentioned in the javadoc for Language
enum:
In order to support a new language, you need to add it here and then implement
the GsubWorker for the given language and return the same from the
GsubWorkerFactory.getGsubWorker(org.apache.fontbox.ttf.CmapLookup, GsubData).
This change set also contains final changes to make Bengali feature complete.
Thanks,
Palash.

> 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.
