    For more info on End-User-Defined Characters (EUDC) in MS products, see:

    Especially that second entry, which mentions the PUA explicitly.

    While it is certainly possible for the PUA to be important for specific
    purposes, the needs are usually temporary, as compared to EUDC, which in
    most cases is never temporary. Thus for every one person cursing the
    implementation there are several dozen or more who are praising it.

    And of course no one should be assuming what an OS is going to do with a PUA
    character unless the OS agreed to do it.

    EUDC is not as "corporate" thing; it is characters defined by end users.
