Incidentally, reviewing Pullum and Ladusaw (1986) to help provide the definitive answer on the retroflex thread reminded me that we knew about these things back in 1989. Pullum and Ladusaw (1986) give, on p. 228, a rectified version of a chart of Russian palalized consonants from Catford (1977), Fundamental Problems in Phonetics. That chart lists: p, b, m, f, v, t, d, n, l, r, s, z all with palatal hooks. (Two were corrected by Pullum and Ladusaw from the actual glyphs that Catford used.) The same list can be seen on p. 263 of the 1996 version of Pullum and Ladusaw. But we saw no evidence of general use of these characters. In fact, the n-palatal-hook form shown there put a hook on the *right* leg of the n, easily confused with an eng and not matching the left-leg-hooked n U+0272 LATIN SMALL LETTER N HOOK widely used for a palatal nasal stop in IPA. So the list from Pullum and Ladusaw was *deliberately* omitted from encoding back in 1989 when the candidates for the IPA extensions were originally assembled, using Pullum and Ladusaw (and other sources), and in direct consultation with Geoffrey Pullum at one point. So once again, I would like to see evidence of use of these characters in a context where available alternatives are not feasible, before we just go ahead and encode a bunch more characters for these. --Ken
