The representation of affricate consonants in the IPA is somewhat problematic. Because they indicate a transition between a stop and a fricative articulation, they’re prototypically represented with sequences of two symbols: [ts tʃ dz dʒ] etc. However, because some languages distinguish stop-fricative sequences from actual affricates, several solutions have been proposed. The one currently accepted by the IPA is to connect both glyphs with a tie bar: [t͡s d͡z] etc., but ligatures such as [ʦ ʣ] etc. are still very often seen in the literature, especially in dictionaries and in Chinese linguistics. Source Sans currently supports two of these: U+02A4 ʤ and U+02A7 ʧ.

Still missing are: U+02A3 ʣ (= [d͡z]), U+02A5 ʥ (= [d͡ʑ]), U+AB66 ꭦ (= [d͡ʐ], added in Unicode 12.0), U+02A6 ʦ (= [t͡s]), U+02A8 ʨ (= [t͡ɕ]), U+AB67 ꭧ (= [t͡ʂ], added in Unicode 12.0).
