    That's not the only problem. In some languages other ligatures, such as
    fj might be as commonly needed as fi - the set is (intentionally) not
    complete and you should not build your text or technology around them.

    Note that for many languages you need to use ZWNJ to prohibit ligatures
    where disallowed by the orthography. Without that information even
    fairly high end software cannot correctly ligate these languages.

    There are some (in)famous word pairs that are spelled identically,
    except for differences in where the ligatures can go. No software
    can figure this out - that information must come from the author.

    Getting sorting and searching operations to consistently ignore
    the ZWNJ is something that has a higher chance of success, compared
    to making such software handle long lists of ligatures.
