    There is no need for <COMBINING H AFTER>,
    because it can be composed of
    <034F COMBINING GRAPHEME JOINER><H>

    This places CH between
    C WITH UPWARDS ARROW BELOW
    and
    C WITH RIGHT ARROWHEAD ABOVE

    For easy multi-level comparison,
    let us define new characters:
    <COMBINING LEVEL 1 GRAPHEME JOINER>
    <COMBINING LEVEL 2 GRAPHEME JOINER>
    ...

    Then, for example, instead of
    <C><COMBINING CARON><E><S><K><Y><COMBINING ACUTE>
    code it as
    <C><COMBINING LEVEL 1 GRAPHEME JOINER><COMBINING
    CARON><E><S><K><Y><COMBINING LEVEL 2 GRAPHEME JOINER><COMBINING ACUTE>
