At that time, the subtable for Unicode Variation Sequences (UVSes) in the cmap table was not so common, so I provided macuvs.h as a fallback for Adobe Japan1 CID-Keyed fonts. But nowadays the subtable for UVSes is fairly common (IIRC, even Hiragino fonts bundled in OS X Lion 10.7 contained UVS). Moreover, macuvs.h is only meaningful for very limited use cases. If maintaining it is a burden on development, the functionality it provides can be removed at some major version update. YAMAMOTO Mitsuharu mituharu@math.s.chiba-u.ac.jp
