Thought people here may find an OpenType subsetter interesting.

Hi,

If you like to follow / discuss my fonttools work, please subscribe to this group:

  https://groups.google.com/forum/#!forum/fonttools

The code is at:

  https://github.com/behdad/fonttools

My fonttools tree now has three new features:

  * SVG table implementation contributed by Adobe,

  * A new full font subsetter (GSUB/GPOS, CFF, everything), call pyftsubset,

  * A PyGTK-based font viewer called pyftfontview,

The subsetter takes many options, look for Options in the source
(fonttools/Lib/fontTools/subset.py) for now.  I'll add proper usage message
later.  Here's an example invocation:

$ pyftsubset Lobster.ttf L o b s t e r --verbose --flavor=woff
