When the first of two adjacent syllables has the vowel sign U+0F7C, U+0F7D, or U+0F80, and the second has the vowel sign U+0F72, U+0F7A, U+0F7B, U+0F7C, or U+0F7D, both vowel signs take their narrow forms. For some of these combinations, that is not necessary: neither or only one of them should be narrow. With both narrow, there is too much empty space between them.
