Malayalam Chillu characters were and are formed by the display engine. Why
then did Unicode 5.x encode them? Round-trip compatibility? And once code
points have been given, people cannot be expected to use them just as
compatibility characters, whatever they mean. They will find ways to type
them in, will be found in text streams and will have to be shown on
display.
Unicode rightly resisted encoding of character sequences recommended by
national bodies. Devanagari Reph is an example. But this good sense is lost
when the proposal is from influential vendors.
