I believe it's a bug.

https://github.com/contextgarden/context/blob/d025bcdf995be6951f69fed6869048ab22491b9e/tex/context/base/mkxl/font-col.lmt#L278

the newchar[] table, which should contain all chars supported by the
fallback termes font if I'm not mistaken, turns out to have only 392 chars
within 0x20-0x30C, far away from 0x2329-0x232A.
