    Are ligatures what I’m looking for? The letters of the consonant cluster
    like "kw" are not joined together visually in any way. Also, when I use
    OpenType for ligatures like ffi st etc. the parts of the ligature are
    deleted one at a time. I think the UAX#29 or UAX#28 discusses the
    differences between grapheme clusters and ligatures.

    There is no locale setting. The Native American language has a very small
    speaker base.

    In fact, I have been continuously sending them lists of all the reasons
    not to use PUA, the CJK problem being only one of many. The problem is,
    they feel the PUA solves their two biggest issues, backspacing the
    clusters and collation, without realising that a whole new and bigger
    batch of problems arises.
