Well there's something wrong with the POST table of the font, and the unicode values of many, if not most, characters are incorrect.
But the rendering behavior you're seeing is because of poor hints, in particular the hints for the curved vertical strokes, between 9-27. The gasp table does indeed call for grid fitting at those sizes, but the stem values fail, leaving them poorly rendered. You would get better results with the Freetype autohinter, I'm afraid. -- Jason Campbell [email protected] www.campbellgraphics.com www.campbellcomics.com Join me on Facebook: facebook.com/CampbellComics <http://facebook.com/CampbellComics>Follow me on Twitter: twitter.com/campbellgraphic 781-799-0457 On Thu, Jul 18, 2013 at 8:43 AM, Tudor, Dacian <[email protected]>wrote: > Yes, using this font is mandatory.
