So, are you going to remove them?

Well, English Wikipedia's article on font hinting gives examples with
curvy shapes and, while I'm not experienced with true type instructing,
I feel it's a language powerful enough to handle all kind of shapes if
you spend enough time to program it.

That's useful information. I spent quite time to remove instructions
from each glyph using the menus whereas it could have be done with one
short sed command! :)

I'm not sure. Screenshot was made from
http://www.cdacmumbai.in/projects/indix/. You can try to understand
what's the point size from looking at this page (boring work since there
are tables, external CSS and weird percentages). It seems it's around
12pt.
Anyway with current instructions it looks bad at all small sizes.

What about "locl" based Marathi specific glyph? (please answer in
initial thread or create a new one dedicated to "locl" feature)
