ICU usage in Swift

[SDGGiesbrecht (Jeremy David Giesbrecht)]

I asked about the status of ICU (or whatever standin) in the compiler itself over in another thread and still have no answer. Maybe someone here knows?

While I realize the compiler and the standard library are distinct, I am not sure how much their dependency requirements affect each other. Anyone working on this should probably be aware that access to some form of Unicode normalization will be required for the other.

Pitch: Unicode Equivalence for Swift Source

I am less familiar the compiler than I am the other parts of the project written in Swift. I have heard mumblings about ICU vs no ICU in the compiler and I don’t know what the actual reality is. Is there easy access to a string normalization function inside the compiler, or will it require modification to even get access to that ability? (It may take some time before I get to this. If someone beats me to it, I won’t hold it against you. )
