I confirm that this now works using the current --context=alpha
\enableregime[utf]
mkiv is utf by default -)
(But is still necessary to remain compatible with mkii)
the \alpha shows up, the α not (not sure why)
you need the mathematical alpha
\startTEXpage \startchemical[width=fit,height=fit] \chemical[ONE,Z0,MOV1,SB5,Z0][C_{\alpha},C_{\utfchar{"1D6FC}}] \stopchemical \stopTEXpage
OK, I see that TeX input is to be retained... However, note that $K_α$ works, so there must be some confusion in interpreting unicode characters in the macros.
