Yeah, I'm very happy to know what you want to do.

Oops, please don't call "TrueType-format file with PS-outline" as OTF.
Yes, Microsoft uses the extension ".ttf" for "TrueType-format file with
TrueType outlines" and ".otf" for "TrueType-format file with PS-outline"
(possibly "CFF OpenType" is proper name), but the OpenType font format
specification covers both category. The critical difference of OpenType
and TrueType is the exist of special layout system with glyph transformation
tables like GSUB, GDEF, GPOS, BASE and JSTF.

However, usually "CFF OpenType" has "CFF" table instead of "glyf" table,
you can exclude it by "CFF" existence, I suppose.
