Hello -- running your sequence through UniView
(http://rishida.net/scripts/uniview/) shows me that the sequence you
have used is actually RA + VIRAMA + ZWJ (and not RA + ZWJ). However,
ever since the encoding of the atomic chillu-s, the above sequence is
no longer recommended for producing the chillu-RA because it would
cause distinct encoded sequences to be rendered the same.

As such I think it is not advisable for HB to support the old sequence
RA + VIRAMA + ZWJ. Behdad might like to ask about this on the Unicode
(or Unicore, if he has access) before implementing support for those
old sequences.

Can you clarify what you mean by *post*-base LA? You mean *sub*-base
LA? Because AFAIK only YA and VA have post-base forms, but perhaps I
am mistaken...
