    OK, I see your point, that we want to look only at characters in current
    use. Well, a good place to start is Michael Everson's report on the
    Alphabets of Europe, The Avar
    script,, is a good example of one
    using palochka, as part of several digraphs; this is a well-established
    literary language and I believe this orthography is still in use.

    And Azerbaijani,, is a
    good example of a language using the apostrophe, as a full part of the
    obsolescent Cyrillic alphabet, and also in the now current Latin
    alphabet although the recent unofficial trend is to drop it.

    While the apostrophe is not perhaps essential for Azerbaijani, it plays
    a much more significant role in the (ASCII-only) Uzbek Latin
    orthography, where it plays two roles, both indicating a glottal stop
    (as in Azerbaijani) and as a modifier of the preceding o or g (i.e. as
    part of a digraph). The name of the country in its own language,
    O'zbekistan, cannot be spelled properly without the apostrophe. See for the alphabet,
    and for detailed rules about the

    But then the apostrophe is also required for the proper writing of
    western languages. In English it is used mostly in contractions and with
    the possessive suffix, and so is somehow not considered a proper part of
    the alphabet - although it is also required for the proper spelling of
    names like O'Connor. But in other languages like French the apostrophe
    marks an obligatory contraction, and there are many phrases and proper
    names which cannot be properly spelled without it. So I could make a
    good case for allowing the apostrophe in IDNs, which should be able to
    represent properly personal and company names etc.

    On the other hand, there are quite a number of your listed atomic cased
    Latin letters which are not in current use, although it is dangerous to
    say that they will not be used because some of these older orthographies
    are being revived.
