Not really, since 'GPOS' is much more powerful. For example, you can disable, say, the kerning between 'f' and 'ı' for Turkish. On the other hand, data in the 'kern' table can't be handled specially for certain scripts and/or languages. However, in its most basic, 'classic' functionality the 'kern' and 'GPOS' tables do the same thing. Werner
