    I *do* mean kerning, but in Font Creator this is called *positive* kerning,
    which increases the space between two glyphs which would overlap when not
    kerned. Usually kerning is taken to mean *decreasing* the space between two
    glyphs like VA, which seem to be too far apart. Please note: I'm talking
    about adding kerning information in a font file, not about kerning within
    an application like Word.

    Creating separate glyphs for pairs of characters is IMO a bad solution: none
    of these glyphs is present in Unicode, so they have to be implemented in the
    PUA, where no compatibility can be guaranteed. Adding kerning information to
    a font is a very simple and straightforward procedure. The results of
    kerning can be beautiful or terrible, depending on the good taste of the
    font designer, but this is also true when separate ligature glyphs are
