    Having a precomposed character isn't really the issue. In OpenType, a font
    vendor can supply a glyph for a non-composed character essentially just as
    easily as supplying a glyph for a precomposed character, by adding a
    ligature or using mark positioning. The more interesting issue is for the
    font vendor to know which glyphs (whether for precomposed characters or not)
    are needed for the markets they are targetting. It's typically not all
    possible glyphs, since that is simply too expensive to do in all faces.
