    These are matters for the font. This kind of horizontal and vertical
    kerning can be done easily with modern technologies.

    This is a matter of fonts, not of renderers. Most modern text renderers
    are capable of displaying either 00B7 or 2027 correctly if the font is
    set up for that, e.g. to display them as ligatures, or to move the dot
    depending on context.

    If these are ligatures, they don't need their own Unicode code points,
    and such code points should be treated as alphabetic presentation forms,
    included onyl for compatibility reasons.
