Thanks.  In the mean time, Jonathan was kind enough to compile a list.  Here
it is:

U+0AC9    => 0AC5 0ABE
U+0B57    => no decomp, -> RIGHT
U+0F77    => 0FB2 0F81
U+0F79    => 0FB3 0F81
U+17BE    => 17C1 17BE
U+17BF    => 17C1 17BF
U+17C0    => 17C1 17C0
U+17C4    => 17C1 17C4
U+17C5    => 17C1 17C5
U+1925    => 1920 1923
U+1926    => 1920 1924
U+1B3C    => 1B42 1B3C (?) Balinese
U+1C29    => no decomp, -> LEFT
U+A9C0    => no decomp, -> RIGHT
U+1112E    => 11127 11131
U+1112F    => 11127 11132
U+111BF    => no decomp, -> ABOVE
