Why do I see Asian characters when I enter certain characters (such as epsilon with circumflex) with GreekKeys Unicode input?
Because of the slow spread of support for smart fonts with ligature features, GreekKeys Unicode fonts from New Athena Unicode v.2 onward use Private Use Area (PUA) code points for some complex combinations (such a vowel with macron or breve and diacritics). The drawback of using PUA is that conflicts are possible. If a system font is present using the same code points in PUA, then OS X will take the character from that system font and not from New Athena Unicode. For a brief period and only in some installations of Panther (10.3), Apple was distributing a font that uses PUA code points that conflicted with those in GreekKeys Unicode fonts, but the font was later changed so as not to use these code points. The conflict should disappear if you upgrade your Mac OS to a more recent version. Before doing anything to your Panther system (again, this does not apply to Tiger or later), verify that there is a conflict and identify which font causes it.
