First of, thanks for the great plugin.
I've got a bug though - it seems that the soft hyphens appear as actual hyphens in Chrome (at least some of them), even when not at the end of a line. Here's a screenshot http://iliadraznin.com/wp/wp-content/uploads/2010/12/typoeg.jpg
At least I think these are soft hyphens, since using chromes developer tools and looking at the source code the character doesn't appear, so not sure what's going on here.
(I'm using latest WP, which is 3.0.2 and latest wp-typography - 2.0.2 and Chrome 8.0.552.215 beta)
