Re: On the upcoming LATIN LETTER SMALL CAPITAL Q

[Denis Jacquerye]

For what it’s worth, the small capital q was used as an IPA symbol for a
while. It was used for the Arabic ʻayn as a “consonne roulée gutturale” in
the 1898 IPA chart (previously noted 3 in the 1894 IPA charts and ᴈ in some
1895 IPA charts and later charts) then as a “consonne fricative bronchiale
sonore” in the 1905 and 1908 IPA charts, and in the notes after the IPA
chart in 1912. It was eventually replaced with the reversed glottal stop ʕ,
for example in the 1932 IPA chart or later charts.
