OK, so it's obvious by now I'm not a font guy. But I still maintain that there's more to proper handling of Unicode characters, PUA or otherwise, than whether their directionality is LTR or Arabic-RTL or non-Arabic-RTL or what have you. That's why all those other properties exist. And I maintain that PUA users need a place to store those other properties, and that the font doesn't seem like the right place for non-display properties. -- Doug Ewell | Thornton, Colorado, USA | RFC 5645, 4645, UTN #14 www.ewellic.org | www.facebook.com/doug.ewell | @DougEwell
