Bengali script repha

Which consonants in the Bengali script may form repha?  In particular,
is the encoding just <U+09B0 BENGALI LETTER RA, U+09CD BENGALI SIGN
VIRAMA>, or can it legitimately also be encoded as <U+09F0 BENGALI RA
WITH MIDDLE DIAGONAL, U+09CD>.

The problem we are having is that some people are encoding Pali 'v' as
U+09F0 RA WITH MIDDLE DIAGONAL, rather than U+09F1 BENGALI LETTER RA
WITH LOWER DIAGONAL, and in some fonts (renderers?) the 'vy' cluster is
being rendered with a repha as though it were <U+09B0, U+09CD, U+09AF
BENGALI LETTER YA>.

Should using the joining sequence <U+200D, U+09CD> prevent repha
formation when the preceding character is U+09B0?  TUS appears to only
define the behaviour between RA and YA, not between RA and other
letters.

Richard.
