/* The spec says U+0952 is OT_A. However, testing shows that Uniscribe
* treats U+0951..U+0954 all behave similarly.
* TESTS:
* treats a whole bunch of characters similarly.
* TESTS: For example, for U+0951:
* U+092E,U+0947,U+0952
* U+092E,U+0952,U+0947
* U+092E,U+0947,U+0951
* U+092E,U+0951,U+0947
* U+092E,U+0951,U+0952
* U+092E,U+0952,U+0951
