    OK. Here's a proposal. There are very few ligatures in the Latin
    alphabet (only the ones you've mention are in actual use, I
    believe), so we can hardcode a different/special behaviour for
    these. Selecting an 'fi' ligature should select approx. half the
    glyph. This will work adequately. There *will* be some overlap,
    but that's not really a *big* problem. Note that there will also
    be some overlap when selecting kerned characters (I certainly hope
    Pango supports kerning!). E.g. in the string 'Ty', most of the 'y'
    will be positioned under the crossline of the 'T', and selecting
    the 'y' will also mark part of this crossline. Again, this is IMO
    not a problem.

    In other cases (Arabic &c.), we should select the entire glyph (or
    do whatever other Arabic-aware WPs do).
