------------------------------------
* +{color:#333333}What is the story of having different data for jdk7 and
jdk8{color}+
Out of 323 entries for the GSUB table for the Bengali-Lohit.ttf font, I am
getting a single entry which differs for jdk1.7 and 1.8. Thats the reason I had
to create the 2 files. I am still investigating this, so maybe, I will come up
with a better solution when I get to the bottom of this
* +I'd also need to know where this file came from, or whether you created it
yourself from other data+
Those .txt files are simple reference data used for testing the correctness of
the GSUB tables. I have created them by putting some logic, transforming
unicode characters into base-10 numbers.
* +BengaliPdfGenerationHelloWorld should be integrated into the
EmbeddedFonts.java example+
Will do
* +why a log4j2.xml ? We don't use log4j2 except in preflight where log4j is
used in Tests+
Agreed, I will remove the log4j2.xml
* +You disabled subsetting+
I don't understand that yet. Please bear with me, I will make it work even with
that. Let me take a look.
* +The move of GlyphsubstitutionTable+
I can move it back if it simplifies things. Should I?
* +There is a lot of logging done+
Will do
* +Loosening scope restrictions is a bit of a no-no+
Agreed. I did this as a part of the move of GlyphsubstitutionTable, if I undo
the move, this will be taken care of.
* +Public methods should have a javadoc+
Will do
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.
