Yes, this is what I mean. I am
astonished that there is no phonetic font presenting this symbol.
Especially since we know that an update of IPA is from 2005 !
Why do you think SIL or other fonts
makers neglected to present this only symbol ?
Because, as I explained, it is encoded in Unicode as a sequence. (See
http://www.linguiste.org/phonetics/ipa/chart/.) Otherwise there would
be 5x5 = 25 different code points required for simple 2-height tones,
5x5x5 = 125 different code points for 3-height compound tones, and so on.
The combinatorial explosion is intolerable.
