    This could be addressed differently: the IDN could include an extra set of
    decompositions which are not in Unicode. Ofcouse the IDN authors would seek
    for advice at Unicode to see if those extra decompisitions affect the
    linguistic. But if there's no evidence that this may be detrimental to
    Yiddish (or possibly other languages using those ligatures), what would be
    wrong if the NamePrep algorithm included extra decompositions?

    Is it up to Unicode to fix that? May be Unicode could simply publish its
    list of confusive characters, and let third-party applications (like the
    IDN) which of them to apply in their algorithms. (Unicode already documents
    several folding algorithms that are not normalizations, and that all are
    optional, whever to use them or not is left to the users)

    This won't affect the statiblity of Unicode itself, but is the IDN
    specification *stable* for now? I know it has several specifications, but
    many revisions as well. Is there a registry which accepts those Yiddish
    ligatures for now?
