    Does anyone have any projects which use UTF-8's or BOCU's binary
    sorting order, and are benefitted by the fact that these formats have
    a sorting order equivalent to the sorting order of the same string in

    I'm more interested in real world projects in use today, that make
    use of this binary sorting order, than theoretical cases where it
    could be useful.

    I personally make use of a lot of UTF-8's properties, especially the
    "no UTF-8 character can exist within another UTF-8 character"
    property, but the binary sorting order property I don't actually use.
