    Googling KA + AU(vs) gives two pages of hits, mostly purporting
    to be Unicode Malayalam text. Searching KA + AU(lm) gives only
    eight hits, none of which are Malayalam text.

    Quoting from:

    Quoting from

    The user community, far as I can tell, shuns the notion that U+0D4C and
    U+0D57 are equivalent.
