    Surely not, or at least only if qualified by the word "Greek". The IPA j
    is surely a normal Latin j, although pronounced as in German rather than
    as in English.

    Greek YOT is a rather different animal, see As is written there:

    - with a link to, which
    discusses issues like Kurdish Q and W and mentions Wakhi as another
    script mixing language - also Byzantine Greek. (But the page title is
    unfortunate although amusing: the Wakhi people are not Kurds.) Well, it
    does seem inconsistent that Unicode has accepted yot as a character to
    avoid script mixing in Greek phonetics, but allows script mixing in
    Latin-based IPA phonetics, as well as in general use in Kurdish and
    Wakhi. That doesn't seem very consistent to me.

    But there are non-casing characters in casing scripts, e.g. Cyrillic
    palochka, apostrophes etc used as letters in some scripts, and arguably
    German sharp S.
