    There are ways to do this in an OpenType font, but it is definitely easier
    to do if you start from separate i and j characters, each followed by an
    acute accent and which may be ligated or not during display, than from a
    single ij character, which would need to be split into two glyphs, have the
    acute accents contextually reordered, and then possibly recomposed as a
    2-component ligature. The latter would require half a dozen lookups,
    including contextual substitutions, to handle what could be done done with
    one simple subsitution and one positioning lookup.
